INTRODUCTION
This technical note documents the procedures utilized in processing
Coastal Zone Color Scanner (CZCS) satellite images for the extraction of ocean
optical properties for the Submarine Laser Communication (SLC) program.
These procedures were used during 1985 and 1986 to generate charts of
ocean properties under the "MOOP" (Modeling of Ocean Optical Properties)
program.
The note contains three sections. The first section consists of procedure
memorandums. A summary memo gives an overview of the major steps in the
processing. The steps include the archival of the tapes and transparencies of
satellite scenes, the extraction of sample scene radiances, the computation of
diffuse attenuation coefficient (K) for the water, and the sorting and plotting of
the K values. The summary memo and flowchart are followed by memos which
document each block in the summary more specifically. These were written by
a variety of authors, as noted on each memo.
1
The second section includes documenting information on the image
processing (IP) system used for much of the processing. A flowchart of the
system hardware is included, along with lists of the IP operations and the
available hardware and software.
The third section contains historical flowcharts showing procedures used
during 1984. The main differences between these early procedures and the
more current ones shown in Section I are discussed briefly in Section III.
The results of the data processing are given in Technical Note No. 205.

SUBJ: MOOP Procedures
At this point we have documented the procedures used in
MOOP standard processing. The major steps are summarized below,
and illustrated on the attached flowchart. The memos documenting
each of these steps are also listed below; the flowchart has been
extracted from each memo and is duplicated here.
1) Transparency check-in; MP85-009t.
As NASA processes CZCS satellite data, they send a
transparency for each scene. This transparency is
a photographic image of the scene as recorded in
each of 6 spectral bands. Transparencies are
checked-in and stored in notebooks in orbit order.
•
2) Tape check-in; MP85-006t.
NASA sends tapes containing data for up to 3 scenes
each, along with supporting documentation. Informa-
tion such as scene date and location are extracted
from the documentation and entered in our computer
file which constitutes a scene library. Tapes are
labeled and stored. These tapes are called CRT tapes,
or calibrated radiance and temperature tapes.
3) Scene and Area Selection; MP85-018t.
When we wish to extract data for a given part of the
ocean, the scene library file is used to generate a
list of scenes which are in the area of interest.
MP85-022t
13 August 1985
Page 2
Scenes are selected from this list based on specific
criteria. Next, specific portions of the scene,
known as areas, are chosen for processing. Whereas
a scene consists of 1968x970 picture elements, an
area is a 512x512 portion of the scene which will be
further reduced to 256x256 during processing.
4) Area Processing; MP85-019t.
Once a specific area of a scene is chosen, the CRT
tape containing that scene is found. The computer
then reads the tape, extracting the data for the area
of interest. As part of the program, the data are
calibrated and navigated, each 2 rows and columns are
averaged, and the resulting 256x256 image for each
band is stored on disk. The results are then trans-
ferred to tape until they can be cell processed.
5) Cell Processing; MP85-021t.
In cell processing, the files on the tape containing
the area processing results are read back onto disk.
An operator views the visible band images (bands 1-4).
For MOOP processing, the global data base is too
large to permit processing all of the full images to
obtain water type. Therefore, at this point, repre-
sentative small samples called cells are chosen for
each area; only these sample cells will be processed
to yield water type. The darkest water, and up to 9
random sample cells are chosen. When an operator
interactively selects a cell, a packet is created
which contains the pertinent information for that cell.
Packets are stored in a file for further processing.
MP85-022t
13 August 1985
Page 3
6) Packet Processing; MP85-020t, and MP85-005t.
After cell processing is completed, the resulting
packet files are combined and run through FINAL CEL.
This program reads the radiance in the four visible
bands from the packet file, along with such infor-
mation as solar zenith angle. On the basis of
Hering's atmospheric model in combination with water
radiance models developed by Austin, Petzold, and
others, computations of water radiance are made.
From water radiance, the diffuse attenuation
coefficient K (which is related to water type) is
derived. A "Klist" is generated containing the
resulting K, location, and related values for each
packet. WAYNECEL is a program similar to FINALCEL
which yields more parameters for Wayne's analysis.
Sorting and Plotting; MP85-005t.
Once the K list is generated, values may be sorted
by season, using program KSORT. They are then
plotted on maps of the appropriate ocean or portion
of the ocean, using program KPLOT. The resulting
plots are the primary deliverable items for MOOP,
along with supporting documentation and analysis.

SUBJ: Transparency Check-In
The transparency check-in steps are listed below and illus-
trated on the attached flowchart.
4)
1) Check the mail every day for new transparencies.
2) If there are transparencies, initial the shipment
receipt and also date it. When there are enough
receipts to fill an envelope, send them to the
address listed on the shipment receipt.
Arrange the transparencies in order by orbit and
then start time. Both are to be put in ascending
order.
Count the number of transparencies received. Each
orbit has a shipping letter which tells how many
transparencies are in that orbit. Record the total
received and date on the appropriate list in the
processing room.
5) Place transparencies in plastic sacks and then file
the transparencies in the correct folder. The
folders are in order by orbit.
If there is a duplicate transparency, remove the one
with the earliest version number. The version number
is located in the lower right hand corner of the
transparency.

SUBJ: Tape Check-in Procedure
I. TAPE CHECK-IN INITIAL PROCEDURES
UNPACKING TAPES
1) NASA CRTT tapes are delivered to drafting building.
2) Unbox tapes and documentation (1 page per tape).
a.
The documentation contains:
tape #, target area, time, orbit, etc.
#
#
#
#
3) Match the tapes with documentation. This is done
by control number (LL# ###L) located on tape label
and written on upper right hand corner of documen-
tation. If no control number exists, this can be
done using run number. (Fig. 1). If no control
or run number exists, set aside for special
handling. (See Appendix A).
Make sure the number of tapes received matches the
number of tapes noted on the invoice. Date and
initial the invoice.
11
a. One copy of the invoice is kept for our
records in the lower left drawer of the
processing desk.
The other is returned in the envelope
provided.
5) Tape a number on the stack of tapes and write this
number on the corresponding stack of documentation.
6) Continue steps 1-5 until all boxes are unpacked.
Make sure to increment the number attached to each
stack of tapes.
MP85-006t
12 February 1985
Page 2
ASSIGNING TAPE # OR VLN'S
1) Get the next VLN to be assigned from the in-box on
the processing desk.
2) Number each sheet of documentation starting with
the number obtained in Step 1, and incrementing by
one. These are assigned sequentially.
3) The smallest number should be at the bottom of the
stack, the largest at the top.
4) Record the next VLN to be assigned.
RECORDING DOCUMENTATION (ENCODING)
Record the information from the documentation sheets
to worksheets.
a. Fig. 2 has all the information to be
transferred to worksheets highlighted.
Fig. 3 is an example worksheet taken
from Fig. 2.
2) The control number is only recorded on the line with
file pair one.
3) The version # (from Fig. 2) is the same for all docu-
mentation.
4) Starting with file pair one:
a. When recording orbit, supply leading zeroes
to orbit if under 5 digits.
Case 1 (1 target area in file pair)
a. Record orbit, date, year, hr/min/sec
(time), number of lines and control
number if this is the first file pair.
Case 2 (2 target areas in file pair)
a. Repeat above steps for one target area.
b. On the next line record a 99, as shown
in Fig. 3.
c. On the next line record the orbit
number and record the second target
area in the space provided for DAY.
MP85-0060
12 February 1985
Page 3
ce
Case 3 (3 target areas in file pair)
a. Repeat steps for Case 2.
b. Repeat Case 2b and 2c using the
third target area.
5) Do these steps for each file pair.
6) File the documentation in the appropriate notebook
located in processing room.
Note: Only follow this procedure for distinct target
areas, not for repeated targets in the same file
pair.
MAKING STICKERS AND LISTINGS
1) Key data into computer from worksheets, using the
editor. Name the file 'INSERT'. An example of
INSERT is located in Fig. 4. Note the number of
lines in this file. This is needed for next step.
Spool and check for errors before proceeding.
2) Create the stickers and a listing of the tapes.
a. After the OK prompt, type:
SEG STILLMAN>ORBITLZO
This creates two files. STICKR which
contains the labels for the tapes.
(Fig. 5). FINAL which is a listing of
the tapes. (Fig. 6).
3) Spool STICKR. Put stickers on Tapes.
4) Rename FINAL to FINAL.date.
5) Use the SORT command on columns 1-5, putting the file
in orbit order. SORT is a PRIMOS command.
6) Several FINAL's can be sort merged together and called
UPDATE.date.
7) Use the FUTIL command to transfer these files to SATELLITE.
8) Quarterly, these files can be merged with ORBIT.MASTER or
TARGET.XXXXX, as noted in Quarterly Procedure, "Merging
w/Master Files".
MP85-006t
12 February 1985
Page 4
II. QUARTERLY PROCEDURES
QUARTERLY PROCEDURE FOR SPECIAL REQUESTS
1) Using the files named UPDATE.date, merge all files
with this name type. These should be sorted
according to orbit, date, and target. Use the
PRIMOS command SORT-MERGE. These files should be
error free, so if you haven't been checking for
errors all along, do so now (the things you should
check for are listed in the next step). Call this
file date. WORKFILE.
2) Check the files for these kinds of errors:
a. the orbit numbers should increase as the
date increases.
b. impossible times (only 24 hrs/day, 59 min/hr);
these errors can be corrected using the
original documentation found in the documen-
tation files.
3) Using the special request notebooks located in the
processing room, start going through the computer
printout of the files mentioned above looking for
matching orbit numbers and times.
4) If a match is found, place a plus sicn (+) in front
of the target number for that orbit and time on the
computer printout. Example in Fig. 7.
On the Special Request sheet, write the VIN number in
the appropriate column. If this is a new plus (there
are no previous VLN's) add a one to the count of
special requests received. This paper is located in
the processing desk.
6) After going through the whole list of requests, use
the editor to add the plus' to the files.
5)
Use
MP85-0060
12 February 1985
Page 5
MERGING WITH MASTER FILES
1) Use the SORT-MERGE command to merge the ORBIT.MASTER.date
with the date.WORKFILE. This should be sorted by orbit,
date, and target. The final file should be called
ORBIT.MASTER.date.
2) Now, use the editor to make a copy of the ORBIT.MASTER or
use the copy command in FUTIL. call this file TEMP.
3) Sort the TEMP file by target, then orbit, then date.
This means you will have 3 sort keys.
4) Now, use the editor and unload several target areas into
a file. Call these files TRGTS.THRUXXX, where xxx is the
last target number in that file.
TO CREATE FILES WITH HEADERS
1) You will need to be in directory STILLMAN. Edit the file
called CZ.RUNOFF so that the date is today's.
2) Edit the file called ENDING, so that the number of
Special Requests received is the new total. Don't include
duplicates.
3) Now prepare TEMP for RUNOFF. You type everything that's
in capital letters:
1111
ED TEMP
LOAD CZ.HDR
LOAD CZ.RUNOFF
MODE NU
T, P03
/* optional, just a check */
LOAD ENDING
FILE
The OK prompt should appear. Now type:
RUNOFF TEMP
output file date.ORBIT.RUN
MP85-0060
12 February 1985
Page 6
This file is very long, so make sure that people are
warned and that a new or farely new ribbon is on the
printer and there is plenty of paper.
4) Spool date.ORBIT.RUN three times. Send a copy to:
a. Gail at SSOF #A030
b. Charleen Epstein X-2350 at #A014
Retain one copy for us.
5) Delete TEMP.
6) All the target files and the orbit files should be
FUTIL-ed to SATELLITE. Keep a copy of the orbit master
on tape or in your file where no one will use it. This
is done just in case someone accidentally messes up the
files in SATELLITE. Now, there is always a back-up.
7) Delete all old files in SATELLITE.

APPENDIX A
NASA CRTT SATELLITE TAPES WITHOUT PAPERWORK
The following is a procedure to read leading documentation
from CRTT tapes into a file. The file should then be spooled and
the information needed for the worksheets extracted.
a. Assign Tape Unit 0, 1, or 2.
AS MTX
b. Assign a disk
AS D XXXXXXX
Also creates a como file. Type: COMO TYPE
This creates a file called TAPE in your directory
which is a copy of everything that goes to the
screen.
c. Enter Image Processing System.
d. Use op 177
e. For the first file pair type in:
O to read header
1 to read leading documentation
7 to skip one file
f. After this, do a C (Control C). Which gets you
back to the OK prompt.
g. Repeat steps (e) and (f) for file pair two.
h. For file pair three repeat step (e), except do not
use option 7. You are already at the end of the
tape.
i. Select op 64, to rewind the tape.
j. Select op 45, to exit the Image Processing System.
k. Type: COMO -E
This ends your como file.
1. Spool the file called TAPE.
If you do not wish to use the como procedure, at op 45
when it asks you if you want to delete the printer file, answer
NO (or 0). Then spool PRINTER.

TECHNICAL MEMORANDUM
MP85-0187
8 July 1985
TO:
Distribution
FROM: M.E. Karr and J.E. Shields
SUBJ: MOOP Scene and Area Selection Procedures
This memo documents the steps required to select CZCS scenes
and areas for processing for MOOP. The following definitions may
be useful:
Target Area: The ocean has been divided into over 200
target areas by NASA. The target areas of data on
tape are given on the tape documentation received
from NASA.
Scene: A two minute sample of satellite data in all
channels. For each channel, a scene consists of
1968 x 970 pixels
Area: A portion of a scene processed using 2x2 averaging
to yield a 256x256 area.
red
In order to generate data for some region of the ocean,
the target areas for that region are extracted from a target area
map. The next steps are then to make a listing of possible
scenes, view these scenes for acceptance or rejection, and then
choose areas from the accepted scenes. The procedures used to
carry out these three steps are given below. The steps are illus-
trated in the attached flowchart.
MP85-0187
8 July 1985
Page 2
I. Create a Listing of Scenes
1. Attach to the Satellite directory
2. EDIT Trgts. Thru020. or
Trgts. Thru040. or
Trgts. Thru090. or
Trgts. Thru190. or
Trgts. Toend.
Comment: The above listed files contain target areas
0 to 20, 21 to 40, 41 to 90, 91 to 190,
191 to end, respectively. Memo MP85-006t
documents the generation of these files.
3. The target area is located in column 32 in the above
listings. So to find your target area of interest type:
F(32) XXX
where xxx is the target area (TA).
Use leading zeroes for TA's less than 100.
4. To get a listing of that TA alone or several successive
TA's, you need to unload that section of the file. To
do this, note the line number of the first entry in your
TA of interest. (Use MODE NU). Then note the line
number of the first entry in the TA immediately following
your TA or TA's of interest. Take the difference of
these two numbers. This tells you how many lines there
are in your TA or TA's of interest. Point back to the
line of the first entry in your first TA of interest. Then,
UNLOAD filename # of lines to unload.
5. If several non-successive TA's are desired, steps 3-4 are
repeated as necessary. Then sort and merge the listings
you have just created. Use:
SORT -MERGE
This Prime utility program will ask you the following
questions:
a)
Enter input filename, output filename and #
of sorts you wish to perform. The input filename
is the first file you wish to sort, merge. The
output filename is the name you wish to give to
the sorted, merged file. You will always perform
2 sorts in this case. A sort is done by TA and
then by orbit.
On separate lines enter the start and ending
column numbers of the items you wish to sort.
Enter: 32 34
1 5
Comment: Sort first by TA located in columns
32-34. Then sort in order by orbit
located in columns 1-5.
MP85-018t
8 July 1985
Page 3
c) Enter the number of other files you wish to
merge. (maximum = 10).
d) On separate lines type the remaining files you
wish to merge. Hit the RETURN key. The
program will tell you when the sort, merge is
completed.
Note: If you wish to create a listing of a
single TA or several successive TA'S,
a sort, merge is not necessary. You
only need to sort, merge if you wish
to create a listing of non-sequential
TA's, for example a listing of TA'S
109, 111, 113 would need a sort, merge.
5. After you have created a listing, enter the date you
created this listing and the name you have given it into
the PACKET notebook, listed under Scenes Log.
II. Select or Reject Scenes
Once the listing of possible scenes is created, the trans-
parency for each scene is viewed and the scene accepted or rejected.
If for some special purpose only certain seasons are desired, the
seasons are defined as given on the "Seasons" list.
Following this page are a list of criteria for selecting a
scene and a list of status codes. The status code indicates that the
scene has been analyzed and gives the result of that analysis. The
code you have given the scene is noted on the scene log.
All rejection codes are to be entered at the furthest right
of the entry. If the scene was accepted, enter a check mark next to
the orbit corresponding to the scene. If a scene is selected, a
sticker indicating the TA and VLN number (tape number) is placed in
the upper right hand corner of the transparency. All accepted trans-
parencies now go in the READY FOR AREA SELECTION bin.
MP85-018t
8 July 1985
Page 4
SCENE SELECTION CRITERIA
MOOP CZCS PROCESSING
A scene may be accepted if it has at least one 512x512
area which meets the following criteria:
1. There must be 512 data lines.
2. There must be at least one 50x50 pixel cloud-free
region. If band 6 is available check it for regions
that are questionable.
3.
If it is too hazy to distinguish cloud holes, reject
the scene.
Within the cloud-free regions in the area there must
be at least 3 points where cells can be pulled which
are:
a. free of overshoot in all bands
b. free of sun glint
c. free of data dropouts
Note that the full cloud hole need not be free of
overshoot, but some portion of it must be definitely
free of overshoot.
The object here is to choose scenes which will yield an
area with at least 3 cells; cells are approximately 150 pixels
apart. In target areas with very little data, scenes yielding
fewer cells may be accepted.
MP85-018t
8 July 1985
Page 5
MOOP STATUS CODES
Status codes are assigned to a scene to indicate scene image
quality. The codes are added to the tape catalog list to indicate
that the transparency for that scene has been examined and the outcome
of that examination.
The status codes that have been assigned here were with 'MOOP!
processing in mind. For this project we are looking for cloud-free
atmosphere areas so that the water radiances can be extracted. Minimum
useful cloud hole is on the order of 50x50 pixels.
There is a degree of subjectivity in assigning these codes.
Therefore, when in doubt, look up the transparency and take a look for
yourself.
All of the codes except 'p' indicate that the scene was
rejected for MOOP processing. If it was processed, an ID# will also
be entered which will allow the processed output to be located. In
some cases an ID# will also be found with a rejection code. For ID#'s
before 1600, no processing was done on the scene data. If the ID# is
greater than 1600 then it means that the scene was rejected after
processing and analysis.
LO
O
B = Bad Data
C = Cloudy. Open areas are not sufficiently large.
(less than 50x50)
G = Sun glint (due to wrong tilt)
H = Hazy. Open areas are badly contaminated by haze,
fog, or thin cirrus clouds. This judgement is
usually made from band 4.
D = Data dropouts. Useful areas are too small due to
satellite data dropouts.
L = Fewer than 512 lines.
0 = Overshoot. Open areas are contaminated by overshoot
in any of the first four bands due to clouds on
the left.
N = No transparency. The transparency associated with
the orbit and start time could not be found.
T = Tape not found in library.
U = Unreadable tape.
P = Processed. The area selected within the scene was
processed to either calibrated radiances, Kor
chlorophyll.
S = Sun too low (less than 10° sun elevation).
F = Fewer than 3 regions for cell extraction; could be
processed to extract 1-2 cells.
I = Not in area of interest.

III. Select Areas
-
-
-
The scene selection isolated scenes which should have a
good area. This step is to merely confirm that selection and
select the exact area coordinates. The criteria for selection are
as listed before.
In order that the 512x512 pixels used to generate an area
not extend beyond the edge of the scene, the following rules are
used.
1.
X coordinates may range from 1 to 1450. There are
a total of 1968 pixels in the x direction. In
computing the calibrated radiance, rows x through
x+511 are used. Ideally the area selected should
be in the middle of the scene. This reduces the
distortion that occurs at the edge of the scene.
Similarly y coordinates may range from 1 to about 450
or be zero. Line numbers start with l at the top,
and lines y through y+511 are extracted. However,
y=0 is a code which instructs the computer to use the
bottom 512 lines in the scene.
3.
Some scenes contain a black block. Do not choose an
area where processing will run into that block.
Note: Because of the subjective nature of scene and
area selection, the area from a scene should be chosen
only after several other scenes (approximately 10)
have been chosen. Upon re-analysis of the scene, you
may find that you would reject it after all.
More than 1 area may be selected per scene; select as
many good areas as possible.
MP85-0187
8 July 1985
Page 7
IV. Follow-up Documentation
After each area is chosen, write the corner coordinates and
tape number on the corner of the transparency and put the transparency
in the area processing bin. Rejected transparencies are put back in
the books. The status codes are then entered in the TRGTS. files.
This completes scene and area selection.
V. Previous Criteria
The selection criteria given in this memo include some changes.
Smaller cloud holes are acceptable, and more haze is acceptable. These
changes are due to our increased confidence in the improved atmospheric
removal algorithm. Also, more data dropouts and overshoot are
acceptable as long as the cells can be chosen in some portion of the
area which are clearly free of overshoot and data drop. For example,
a cloud hole which has overshoot in the bottom half of the hole would
previously have been rejected but now may be accepted as long as cells
are only pulled in the top half of the hole. For reference, the scene
selection criteria used as of July '84 is attached, along with the
codes used at that time.

SCENE SELECTION CRITERIA
FOR
MOOP CZCS PROCESSING
These criteria should be followed when selecting areas to be processed
from transparencies.
1. Avoid any scattered clouds or structure appearing in all bands
that may be a low lying cloud.
2.
If band 6 is available check it for areas that are questionable.
Look for a 200 pixels x 200 pixels area free of solid clouds and
free of overshoot in all bands.
4.
If possible, choose an area closest to the center of the scene.
5. Use a maximum value of 1450 for the x coordinate.
6. Reject if there are less than 512 lines in the scene and label
transparency with code L.
ver
es Or
7. If over 10 missing lines or other data drop outs, reject and
label accordingly.
8.
Check for sun glint effects due to an incorrect tilt.

Previous Codes
Prior to this memo .
MOOP STATUS CODES.
رکوع می
STATUS CODES ARE. ASSIGNED TO A SCENE TO INDICATE SCENE IMAGE QUALITY.
THE CODES ARE ADDED TO THE TAPE CATALOG LIST TO INDICATE THAT THE
TRANSPARENCY FOR THAT SCENE HAS BEEN EXAMINED AND THE OUTCOME OF THAT
EXAMINATION.
THE STATUS CODES THAT HAVE BEEN ASSIGNED HERE WERE WITH 'MOOP' PROC-
CESSING IN MIND. FOR THIS PROJECT WE ARE LOOKING FOR CLEAR ATMOSPHERE
AREAS SO THAT THE WATER RADIANCES CAN BE EXTRACTED. MINIMUM USEFUL
AREA IS ON THE ORDER OF 100*100 PIXELS. OTHER FACTORS WILL INFLUENCE
WHETHER SUCH A SMALL AREA IS USEFUL. IN MUST CASES LARGER AREAS ARE
NEEDED.
THERE IS A DEGREE OF SUBJECTIVITY IN ASSIGNING THESE CODES. IN
ADDITION, WHAT IS USEFUL FOR ONE APPLICATION IS NOT FOR ANOTHER, AND
VICE: VERSA. THEREFORE WHEN IN DOUBT LOOK UP THE TRANSPARENCY AND TAKE
A LOOK FOR YOURSELF.
.
ALL OF THE CODES EXCEPT 'p' INDICATE THAT THE SCENE WAS REJECTED FOR
MOOP PROCESSING. THE CODE IS ENTERED INTO THE TAPE CATALOG SO THAT IT
WON'T BE CONSIDERED AGAIN. IF IT WAS PROCESSED. AN ID# WILL ALSO BE
ENTERED WHICH WILL ALLOW THE PROCESSED OUTPUT TO BE LOCATED IN SOME
CASES AN ID# WILL ALSO BE BE FCK'NO WITH A REJECTION CODE. FOR IDH'S
BEFORE 1600 NO PROCESSING WiiS DONE ON THE SCENE DATA. IF THE ID# IS
GREATER THAN 1600 THEN IT MEANS THAT THE SCENE WAS REJECTED W.FTER
PROCESSING AND ANALYSIS.
B - Bad Data
Ć - CLOUDY. OPEN AREAS ARE NOT SUFFICIENTLY LARGE.
G - SUN GLINT (due to wrong tilt)
H- HAZY. OPEN AREAS ARE CONTAMINATED BY HAZE. FOG, OR THIN CIRRUS

D - DATA DROPOUTS. USEFUL AREAS ARE TOO SMALL DUE_TO SATELLITE DATA
DROPOUTS.
L - Fewer than 512 LINES
O - OVERSHOOT. OPEN AREAS ARE CONTAMINATED BY OVER SHOOT IN ANY OF THE

TECHNICAL MEMORANDUM
MP85-0190
8 July 1985
TO: Distribution
FROM: M.E. Karr, J.J. Johnson, J.E. Shields
SUBJ: MOOP Area Processing
The following pages document the area processing procedure.
The general procedure is to edit the file DATA.IN, which contains
the information which varies from one run to the next. The
phantom file P CPL177CRD is then run. This phantom file starts
the CPL file C_177CRD.CPL. This CPL file in turn does the
following: a) start a como file CHECK.CPL; b) read in the file
DATA.IN, and c) direct the use of 0P177 in IP to read the tape
and extract the radiance images. The resulting como file may be
used to verify the success of the run.
Area processing is illustrated in the attached flowchart.
The procedures are listed on the following pages.

AREA PROCESSING
Fill in the table in the MOOP log book. (see attached page).
You will need to enter the information listed below. Item a is
the next number in the log book; items b-f and j are on the
transparency, and g-h are written on the transparency during
area selection; item i is filled in after area processing is
completed.
sovou o
a. ID# (each area processed is assigned a sequential ID#)
b. orbit number
date, in the form MMDDYY
scene center (the latitude and longitude)
number of scan lines
tilt
the x and y corner from which to start processing.
A 512x512 area will be processed.
h. Vislab number (VLN), each tape upon arrival at the
Vislab is assigned a VLN. This number includes a
file pair number. The file pair number indicates
the scene location on the tape.
i. status code, either a P for a processed image or U
for an unreadable tape.
comments, the start time should be entered in this
column.
2.
Mount the input CRT tape (Calibrated Radiance Transmittance)
on drive 2. Do not assign drive 2, and make sure no one has
assigned drive 25 If someone is using drive 2 and you only
need to read the tape you may use either drive 1 or 0. See
step 11 for procedures.
3.
Attach to sub UFD ATLAS>$CPL>AREA
A ATLAS>$CPL>AREA
4. Edit the file DATA.IN, using the replace command (R). This
file is one line of numbers, separated by spaces. The numbers
are the appropriate values for the following variables:
DISK INSKIP FILE XSTRT YSTRI ID# VLN#
#
where
DISK = 5. All area processing is done on IP disk 5.
INSKIP = number of files to skip on tape. Each scene requires
2 files to be described. There are 3 scenes on a tape
so for the
1st file pair, inskip = 0
2nd file pair, inskip = 2
3rd file pair, inskip = 4

Page 3
FILE = what area number this will be on the tape. 19 areas may
be processed on each tape. So the file number will be a
number from 1 to 19.
XSTRT = the starting x coordinate
YSTRT = the starting y coordinate
ID# = a sequential number assigned to each area processed
VLN# = VisLab assigned tape number, includes file pair number.
so the format is NNNN.n, where NNNN is the VLN# and n is
the file pair #.
Save DATA.IN using the FILE command.
5.
Make sure CZSAVEINPUT exists, if not dummy it, i.e. create an
empty file with this name.
6. Execute the phantom file P CPL177CRD:
PHP_CPL177CRD
The phantom run will take from approximately 15-20 minutes.
If the phantom is still running after 20 minutes there may be
a problem. See step 12.
7. Edit CHECK.CPL to see if run was successful.
a. Go to the bottom (B)
b. Go back up 60 lines (N-60)
c. Print 10 lines to see ID#, IP file, and VLN#.
Make sure the ID# and VLN# correspond to what you
have entered in DATA.IN. An incorrect ID# and file
pair number are errors that can occur. Also check
that approximately 500 lines have been scanned.
Occasionally it is desired to see the amount of money
that was required to run this program. Go back to the
bottom and then come back up 10 lines and then print
10 lines. You will then see the amount of money used.
This may be entered in the comment column for the MOOP
area processing notebook.
15
8. Update the log book by entering a P or U in the status code
column. If there were problems see step 12.
Write p and the ID# on the sticker located in the upper right
hand corner of the transparency. Place processed transparencies
in the CELL PROCESSING bin.
10.
If 19 areas have been processed, they are ready to be written
to tape. It takes 6 files to describe the six individual band
representations of a scene, therefore 114 files can be written
to tape (19x6 = 114). Use Operation 40 in the IP system to
write from disk to tape.
MP85-0190
8 July 1985
Page 4
a. AS D nnnnn, where nnnnn is the physical device number
you will most likely be using D 460
AS MTn, where n is the tape drive number. Either 2 or
1.
oo 4ois
Type IPSHARE to get into the IP system.
Enter what room you are in
e. Enter what disk you are using, you will most likely be
using disk 5.
For number of columns and rows, enter 256 256
For operation, enter 40 (to write to tape).
Enter the file number at which you wish to begin writing,
then the last file number you wish to write to tape.
In response to the prompt RCKFHB, enter zero (0) for
real data. Then enter the number of files you wish to
skip. This number depends on the number of files
already on tape. For this reason it is important to
keep track of how many files are currently on tape. If
this is the first file on the tape, skip = zero (0).
The drive number will either be 1 or 2 since you can
only write to tape on either of these 2 drives.
To get out of IPSHARE, type 45 in response to Select
Operation,
After the files are on tape, rewind the tape and record
the new files written to tape.
These tapes are stored on the wall adjacent to the
printer.
i.
11. What to do if drive 2 or physical device 460 is being used:
a. Edit P CPL177CRD
Change MT2 to MTn, where n is the new drive number
Change D 460 to D nnn, where n is the new disk number
b. Edit C 177CRD.CRL
Point to line 31 and change %INSKIP% 2 to %INSKIP% n,
where n is the new drive number. Do the same at lines
34 and 54.
c. See attached listing for more information.
12. Problems
a. If the y coordinate is greater than 450 and the program
has ended with an error, adjust the y coordinate so that
it is less than 450.
b. If in CHECK.CPL where the program reads the scan lines,
the scan line number does not change
i. Stop the phantom as in step 13
ii. Give the transparency code U (unreadable)
iii. Reassign ID# to next area and use same file
number for next area to be processed
Place transparency in bin labeled
REJECTED-READY FOR PROCESSING CODE ENTRY.
MP85-0191

Page 5
c.
If program ends with error, try cleaning the heads
of the tape drive. The tape drive heads should be
cleaned before and after area processing. After
about 10 tapes have been run the heads should again
be cleaned.
13. To stop a phantom:
a. Type STATUS to find phantom user number
b. Type LO -USER#, where # is the phantom user number.

FROM:
J.S. Fox and J.E. Shields
SUBJ: Cell Processing
This memo documents the operator steps required for cell
processing. This step follows area processing, which yields a
set of 6 256x256 calibrated radiance images, all representing
the same view of the ocean, but acquired in 6 different spectral
bands. Supporting information such as orbit number is contained
in the first image file.
In cell processing, the operator brings the area processed
images up on the monitor for viewing, and then chooses sample data,
designated cells, from the image. A cell is typically 3x3 pixels.
The computer averages the radiance for these 9 pixels, and stores
this radiance and other supporting information as one line of an
output file. This one line of data, called a packet, is then
available for later processing steps.
The cell processing procedure is documented on the following
pages written primarily by J.S. Fox, and illustrated in the attached
flowchart.

CELL PROCESSING PROCEDURES
I.
Loading an Area Processed Tape (in CRT format) on to Disk:
1. Tape Location
a. the area processed tapes that are ready for
Cell Processing are stored on the wall between
the sliding glass door of the Refresh Room and
the hall.
2. Selecting a Tape
a.
The Packet log should be looked at to see which
is the current tape.
3. Reading the Tape
a. Check to see if the write ring is in the tape,
if so, remove it.
b. Mount the tape on a drive.
c. Log in to the Prime, assign the tape drive and
a disk, usually D 10460; attach Atlas and Packet
by the command:
A Atlas > $Packet
d. Into the IP system: Use Iphshare to get in the
IP system. Answer the following prompts like this:
where are you = S
enter Data Disk # = 8
NCOLS NROWS = 256 256
Use OP 41 Tape Read to read the tape.
Check the tape for the total number of files.
Read in all the files you have room for on your
assigned disk. Maximum number of files on tape
is 114.
When the tape read is over, use OP 45 to exit
the IP system.
You should be ready to start cell processing
files you read in.
MP85-021t

II.
Bringing up the area for viewing.
1. You are now outside the IP system with an OK prompt:
Type FASTP Disk # File # Target Area Date
Disk # = the disk where your data is, usually disk #8.
File # = starting file for processing. (See Packet
log for last file processed).
Target Area = the NASA ID for Target Area usually of
the format i.e. TA69
Date = Today's date in the following format: 28NOV84
Having started FASTP, a CPL Program, you will not have
to interact with your terminal until OP 337 is called
by the FASTP program. FASTP will bring the images in
the four visible bands up on the screen.
2.
Image Enhancement by OP 337
a. If all is going well, you should be looking at four
256x256 images.

III. Checking the ident information.
1.
.
FASTP, when OP 337 is exited, will send you to OP 186
and answer the first few prompts, which allow the
system to set up the packet file.
2. At this point check the Info data with the data on
the transparency. Generally, it is only necessary
to check orbit number and start time. If they are
consistent, skip over the "Enter Start-Time Data" and
the "Change Info Data" prompts.
IV.
The Cell Selection Loop.
Once you get by the 'Enter Start-Time Data' and the
'Change Info Data' prompt, you are in the cell selection
loop. The rules for choosing a cell are given in the next
section; the procedures are given here.
1. The first prompt will be the ID. At this point we
generally will not change the ID - (ID is the Area Ident.)
OP 186 prompt: Present ID = ID# Change it?:
D
#
2. OP 186 prompt: Cell Select Key = Image Block #=
For Cell Select key see Table #1. For Image Block #,
see Figure 1.
3.
The next prompt will be for the size of the cell.
OP 186 prompt: Enter Cell Parameters: xsize=ysize=
xpos=ypos=
Before you answer the prompt, move the cursor to the
location you want. Then answer the prompt. xsize and
ysize are generally 3 3 ; xpos and ypos are left blank
so that the computer uses the cursor position.
4. The program will next display the latitude and longitude
of the cell center and prompt the user with:
OP 186 Prompt: Inspect Cell Re-enter
location?
its size or
If you like your pick, answer NO (0), if not, Yes (1).
If Yes, you will loop back to the Enter Cell Parameters
prompt.
MP85-0210
13 August 1985
Page 5
5. If No, the next prompt displayed will be the list of
Cell statistics. If the individual pixels within the
cell are not adequately consistent, you will be notified.
at this point.
OP 186 prompt:
Save This Data.
If you get no error message for bands 1-4, and you
still like the cell, answer Yes.
6.
After Save This Data is answered, the next prompt
encountered will be,
OP 186 prompt: Repeat for New Cell?
7
Answer Yes and repeat the steps given in this section
until all the cells required, as given in the next
section, have been selected. When the last cell has
been selected, answer No to this prompt, and proceed
with Annotation.
V.
Rules for cell selection.
1. Using criteria a-e below, select CELL location represen-
ting the minimum radiance in each band within the target
AREA. (Use Key 2 or 4). (See Table 1 for cell selection
ident nos.)
2. Next, extract cells for grid points, as follows. Use the
Nine Zone Grid as a guide for each of nine additional
CELL locations. (See Figure 2).
3.
If the center of the Grid location meets the CELL selection
criteria listed below, set the cursor and pick the grid
point CELL.
4.
If not, move the CELL location preferably within the solid
square, otherwise within the grid zone (the dashed square)
to a nearby position that does meet the criteria, and pick
the relocated CELL.
5.
If no suitable CELL location exists within the grid zone,
then skip it and move to the next Grid location.
6. Use CELL selection Key 6.X, 7.x, or 8.X, to identify this
procedure. Here X is grid zone number, and 6, 7, or 8
indicates quality as noted below. If a certain grid zone
is skipped, skip the corresponding key.
..
MP85-0210
13 August 1985
Page 6
CELL SELECTION CRITERIA
a. CELL should be out of visible overshoot regions
in all bands.
b. 1) CELL should not include a cloud. If possible,
stay at least 16 pixels from either cloud or
land. If a distance less than 16 must be
selected, use Key Code 8.X rather than 6.X.
Haze in band 4 is 0.K., and uniform moderate
haze in band 1 is 0.K. (Use normal Key 6.X).
If the haze in band 1 is structured or dense
near the CELL, use Key Code 7.X rather than
6.X. If it is very hazy in band 1 (normally
Key 7) and less than 16 pixels from cloud or
land (normally Key 8) skip the grid zone.
C.
6.X = Normal Selection, Light, uniform haze
near CELL.
7.X = Alternate Selection, Heavy or Structured
haze near CELL.
8.X = Cloud/Land Proximity Alert, within 16
pixels.
CELL should pass the flagged criteria AVG/STD > 50
and MIN > AVG-2 STD in bands 1-4. If it does not,
first make the CELL smaller. If 2x2 still does not
pass, move the CELL.
Choose near the center point of the grid whenever
possible. If another location must be chosen, it is
best to choose a location with the predominant water
type.
VI.
Annotation and exit.
1. So we can have a hard copy of the cell selection, a slide
is shot of the four Image blocks we can see, plus
annotation. The procedure is:
a. After you have said No to Repeat for New Cell, next
will be displayed,
OP 186 prompt: Erase cell Graphics Phane(s)?:
Answer No if you want to shoot a slide.
MP85-0210
13 August 1985
Page 7
b. Next question will be:
OP 186 prompt: Display Annotation?:
Answer Yes if you want to shoot a slide.
When the program is done displaying the
annotation, shoot the slide.
The last prompt of the program:
OP 186 prompt: Erase Annotation?:
Answer Yes.
OP 186 is now over.
2.
Exit the IP system, OP 45, or Ex
At this point there should be a file named PKT.data, with a
packet for each cell you have pulled. The full procedure of Steps
II through VI are now repeated in order to pull packets for the
a on disk. You may use the same date on the FASTP prompt,
and the new packets will be added to the end of the file.

FROM: J.E. Shields
SUBJ: Packet Processing with FINALCEL
This memo documents certain aspects of packet processing,
as done in MOOP. Tech memo MP85-020t, documents the generation
of packets using cell processing. Memo MP85-005t shows how to run
these packets through the next program, FINALCEL, and how to sort
and plot the resulting K values. This memo more fully documents
the input and output of FINALCEL as well as giving an overview of
the logic of the program.
A sample packet file is shown in Attachment 1, along with
the names of the variables given in the packet. The listing in
this format is created using the command SPLPKT filename. A brief
definition of these variables is given in Attachment 2, extracted
from memo AV84-054t.
The basic function of FINALCEL is to input the average
radiances listed in each packet, and compute the water properties,
specifically K, the diffuse attenuation coefficient. The general
physics behind this is given in B.M. McGlamery's note, Overview of
MOOP Project Physics. The attached overview of FINALCEL subroutines
lists the function performed by each subroutine. The attached
flowchart gives a very general summary of the functions of the
program. I will not attempt a documentation of the equations used
in the atmospheric algorithm in this summary note.
MP85-020t
13 August 1985
Page 2
A sample of the K list output is attached. This file is
used as input to the sequential sorting and plotting steps. The
details of the inputs used in FINALCEL, as well as the sorting and
plotting steps, are given in MP85-005t.

FROM: M.E. Karr
SUBJ: Procedures for Packet Processing and the Sorting and Plotting
of K Data
The following are the procedures used for packet processing
and the sorting of K data. This memo is an update of memo AV84-058t,
dated 17 December 1984. Note: All user responses are underlined.
0)
A ATLAS>$PACKET>$PROCESS
All processing of packets is done in the $PROCESS sub-ufd.
The data files should be moved from their own sub-ufd to
the $PROCESS sub-ufd. For example, the data file
DB3.PAC.ORB is located in ATLAS>SPACKET>$DB3.PAC, use
the FUTIL command to copy this data file to $PROCESS.
1)
SEG OLEINIK>$SEG>FINALCEL
2) User Input File: USERCELL
The file USERCELL contains the last responses used in
FINALCEL. At the end of USERCELL are 3 file names.
They are the data input file, the output file, and
the Klist output file. If any one of these files do
not exist, you will get an error that reads:
"Open Error for Input Cell Data File." There are 2
solutions to this problem:
1 U
a) Create the file(s) that do not exist.
Use an input cell data file that contains
files that already exist.
MP85-0050
5 February 1985
Page 2
3)
Now you may choose from several options. (See attach-
ment pg. 2 Menu #1). If there will be many changes
to the cell input file, choose Option 1. Where Option
1 will change all parameters. Note: All the following
questions will appear if you choose Option 1.
4) Enter Input Filename:
INFIL
Where INFIL is a group of packet files. The packet
files were created during the cell processing routine.
were crea
Осе
5) Enter Output Filename: DB 3PACPKT
The output filename should indicate the database, the
ocean and the procedure used (i.e. Packet Processing).
6)
Enter Option to Save Klist Data:
1 (YES)
7) Enter Output File for Klist Data: DB3PACKLT
Use same naming convention as in Step 5.
8)
Enter Total Sort Values to Process:
2
(See Attachment pg. 4). This section of the program
is a weed-out section. Read on.
9) Enter Sort Word Number: 48 (SUNZENG)
Enter Minimum and Maximum Sort Value: 065
Now the program will weed-out all entries with sun
zenith angles less than 0 and greater than 65.
10) Enter Sort Word Number: 49 (PIXANG, PIXEL ANGLE)
Enter Minimum and Maximum Value: 065
MP85-0050
5 February 1985
Page 3
11)
Select Algorithm:
2 (See Attachment pg. 5)
This is the atmospheric correction section of the
program. The program will now:
innen
Correct for sensor decay,
2. Compute Raleigh radiances for bands 1-4,
Compute water leaving radiances,
Compute atmospheric transmittance (ground to space),
5. Compute K490.
Enter Option for Iteration Processing: 1
Enter Option for Angstrom Exponent: 1
Enter Scaling Factor for Angstrom Exponent: 1
Enter Option for Sensor Decay Correction Algorithm: 1
(Use Ted Petzold's Exponential Model)
Enter Option to Change Constants for G Function: 0 (No)
SO
are
12) Enter Total Data Words to Report: 8
For final runs report these 8, for test runs report
none unless needed for analysis:
1 = ID#, 5 = KEY #, 12 = ORBIT, 6 = LAVE(1), 7 = LAVE (2),
8 = LAVE(3), 9 = LAVE (4), 201 = K490.
13)
1 (Yes)
Enter Option to Write Report to Disk:
Enter Output Filename: DB3PACPKT
Use the same output filename you entered in Step 5.
14) Enter Option to Print Raw Data: 0 (No)
This option prints the input packet data files.
MP85-0050
5 February 1985
Page 4
15) Enter Option to Print Report: O (No)
e
rt:
This option allows you to print the report to the screen.
If you saved the report on disk, you may see the report
in the output file. The program seems to run faster if
the report is not printed on the screen.
16)
It is a good idea to print the user table if you are
not sure if you entered your options correctly. Use
Option 4 in Menu #1 (See Attachment pg. 2 Menu #1).
17)
Save the user table under a different name if this is a
special case. Otherwise, the user table is automatically
saved under the user cell name you entered in Step 2.
Use Option 5 in Menu #1.
18) Now execute the program. Use Option 3
PROCEDURES FOR KSORT
1)
SEG KSORT
2)
Enter Input Filename: DB3PACKLT
This is the Klist file that was created in FINALCEL.
3) Enter Output Filename: DB3PACSPRO
The output filename should indicate the database, the
ocean and what season and/or K code is used for sorting.
4) Enter Option to Choose Beginning and Ending Dates: 0 (No)
MP 85-0050
5 February 1985
Page 5
5) Enter Option to Choose Season: 1 (Yes)
Now choose a season:
Spring, Summer, Fall, Winter
6) Enter Option to Choose K Code: 1 (Yes)
Now choose a K code: 0-5 or 9
7)
Enter Sun Angle Threshold: I
8) Note the number of data groups read from the input file.
If the input file is sorted by spring, summer, winter
and fall, then the total number of data groups written
to the output files should equal that of the input file.

SECTION III
Data Base II Procedures
This section contains the flowcharts documenting the procedures used
prior to 1983. For this processing, the K values were computed for each pixel in
a full "area" and averages were plotted. This had two disadvantages. First,
processing every pixel to K is slow and expensive. Second, if an improvement
was made in the K algorithm, the processing had to be repeated. The
procedures documented in Section 1 overcome these problems, because
sample radiances are extracted from each area and later processed to K. The
data generated with procedures illustrated in this section were labeled Data
Base II.
