Retrieval of Aerosol from Space-Borne Polarimetric Data in Beijing

It is difficult to determinate the aerosol model when retrieving the aerosol over land surfaces. In this paper, from the products of AErosol RObotic NETwork (AERONET), the aerosol model in city area of Beijing was analyzed. Then, the aerosol properties was retrieved from polarized data of the Polarization and Anisotropy of Reflectances for Atmospheric Science coupled with Observations from a LIDAR (PARASOL), and validated by the AOD products of AERONET. The results show: (1) the aerosol model based on ground based observations in Beijing is different from standard aerosol model of POLDER; (2) the particular aerosol model over Beijing can improve the retrieval accuracy over Beijing.
