Outline of Final Research Achievements

This work intends to develop a procedure to estimate PM2.5 concentration over mega city in Japan. The procedure is composed of two parts as: 1. Aerosol retrieval from satellite reflectance measurements. 2. Conversion into PM2.5 concentration from retrieved aerosol optical thickness (AOT). The comparison of retrieved AOT from GOSAT/CAI with NASA/AERONET AOT measurements is performed in Osaka region. As results, a root mean square error value of AOT (RMSE-AOT) is around 0.09 in all retrieved wavelengths and the RMSE-AOT at a wavelength of 670 nm over Osaka region is around 0.07. Finally, satellite retrieved PM2.5 concentration also coincides with in situ PM2.5 measurements, RMSE-PM2.5 is around 6 ug/m3.
