Comparison of AOD from CALIPSO, MODIS, and Sun Photometer under Different Conditions over Central China

Abstract Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) provides three-dimensional information on aerosol optical properties across the globe. However, the performance of CALIPSO aerosol optical depth (AOD) products under different air quality conditions remains unclear....
