Abstract

We examined three different methods, namely, Method-I, -II, and -III for retrieving local aerosol's optical parameters over the Japan Sea using the ADEOS/POLDER data by comparing with the validation data. Method-I, and Method-II use parameterized directional reflectance and polarization diagrams in two infrared bands, respectively. On the other hand, Method-III uses parameterized directional polarization- reflectance diagrams in a single infrared band. We found that Method-III gives the best agreement with the measured sky validation data. We also presented retrieved distribution maps for the aerosol optical thickness, and Angstrom exponent by Method-III and some discussions on further improvement for Method-III were given.
