AB: The land surface is an emission sources of not only natural aerosols but also anthropogenic ones. It is known that the aerosols originated from the continent are uncertain parameters for the GCM. Retrieval of aerosol properties especially over land is difficult due to variability of surface conditions. This work presents an algorithm for extracting the optical thickness of aerosols and Angstrom exponent over land, which are related to the concentration and size of aerosols, respectively. The basic idea of our algorithm is based on the comparison of observed measurements with simulated values in the polarization field. In this work, we adopt the POLDER (POLarization and Directionality of the Earth's Reflectances) data on board the satellite ADEOS 1 and 2. The POLDER provides us with both of polarization and total radiance at the top of atmosphere. \\ Retrieved aerosol properties are validated by using ground based sun photometric measurements (NASA/AERONET). We also compared the retrieved results from satellite to NIES/CCSR-AGCM - SPRINTARS simulations. \\ It is of interest to enhance that the heavy aerosol loading in the derived global maps is produced over the regions emitting dust, bio-mass burning and industrial waste.
