The predictors in our GAM model include time vectors to represent inter-annual, monthly, and weekday variations, as well as meteorological variables (boundary layer height, east-west wind component, south-north wind component, relative humidity, air temperature, dew point temperature, and surface pressure). The spatial variation in the holiday effect at different sites reflects two distinct ways that human activities impact air quality: increased residential heating tended to increase both PM 2.5 and NO 2 , whereas reduced traffic emissions leads to lower NO 2 . Effects of meteorology and emission reduction measures on air pollution in Beijing during heating seasons	./cache/cord-293139-uj1m3t79.txt	./txt/cord-293139-uj1m3t79.txt
