SPATIAL OVERFLOW EFFECT OF INTERCITY PARTICULATE POLLUTION: A CASE STUDY IN HUBEI, CHINA

Previous studies generally ignored the faint aerosols undetected by the CALIPSO layer detection algorithm because they are too optically thin. Here, we retrieved the faint aerosol extinction based on instantaneous CALIPSO observations with the constraint of SAGE data. The correlation and normalized root-mean-square error of the retrievals with independent SAGE data are 0.66 and 100.6 %, respectively. The minimum retrieved extinction at night can be extended to 10^-4 km^-1 with 125 % uncertainty.
