In addition, for a more detailed analysis over Malaysia, which is only marginally affected by the forest and vegetation fires in the northern part of SEA, the AOD values were extracted for a single pixel Emili et al., 2011 ) that is located over or closest to the 65 monitoring stations including industrial (7), urban (10) cultivation, biogenic emissions, dust, peat and vegetation fires, which explain the comparable or even higher AODs than the urban sites, a large part of the significant AOD decrease at all sites is attributed to the general shutdown of the anthropogenic activities in order to restrict the expansion of COVID-19. ./cache/cord-349078-59wel5o5.txt ./txt/cord-349078-59wel5o5.txt
