Abstract：With the lidar data onboard CALIPSO satellite of National Aeronautics and Space Administration (NASA), the vertical distribution of aerosols when different intense dry haze occurred around Shanghai were revealed by analyzing the parameters including attenuated backscatter coefficient, volume depolarization ratio and total attenuated color ratio. When dry haze occurred, the lower troposphere (0~2km) was polluted most severely with the aerosols whose total attenuated backscatter coefficient concentrated in the range of 0.0015~0.0035km-1×sr-1, volume depolarization ratio and color ratio were centered at 0~15% and 0.2~0.8, respectively. Total attenuated backscatter coefficients within the other altitudes between 2 and 10 kilometers were smaller, ranging from 0.0008~0.0025km-1×sr-1 and 0.0008~0.0015 km-1×sr-1. Depolarization ratio and color ratio for four altitude ranges (2~4, 4~6, 6~8 and 8~10km above ground level) were centered at 0~20% and 0~0.6, respectively. Within the altitude range from 0 to 10 km, the aerosol scattering ability and irregularity during moderate dry haze periods was the strongest and the size of aerosols was the largest compared with slight and mild dry haze periods.
