Abstract

Acquisition of aerosol information on a global scale, especially over the continent, is an urgent task for the better understanding of Earth's radiation budge and climate change. However, it is known that aerosol retrieval over land is much more difficult than that over ocean due to the complication of surface properties. A polarization sensor POLDER boarded on the satellite ADEOS-1 and -2 has shown that the polarization information is useful to extract the aerosol properties such as AOT (Aerosol Optical Thickness), and its wavelength tendency (Angstrom exponent) not only over the ocean but also over the land. Recently the polarization sensor becomes to be noticed. At such a time, this work focuses on role of polarization information from the point of view for aerosol retrieval. As a result, an improved map of aerosol is obtained based on POLDER-2 data. The obtained space based aerosols are examined with the radiometric measurements from the ground.
