Paper Abstract

The retrieval algorithm for aerosol remote sensing has still some problems to be solved. For example, miss-leading of aerosol type selection has often happened due to the difficulties to detect the absorbing aerosols, such as carbonaceous and dust aerosols, over land. The POLDER polarization data are useful to estimate the aerosol information even over land region. This work intends to modify the satellite retrieval procedure by combining the model simulations. The result of numerical simulations is used as a priori information of existence of absorbing aerosols in the atmosphere. Our procedure, in practice, is applied to the POLDER observation period in April, 1997. As results, aerosol optical thickness at three wavelengths are retrieved, and then they are applied to estimate the mass concentration of fine mode aerosols based on the relationship between AOT by ground based sun photometry and PM2.5 sampling. It is found that in April of 1997 the bio-mass burning aerosols are heavily loaded over South East Asia.
