Outline of Final Research Achievements

To aim improving assessment for effects of atmospheric aerosols on earth climate, we developed algorithms to retrieve optical concentrations and particle sizes of several aerosol components (air-pollution, sea-salt, mineral dust, and black carbon) from satellite measurements by two-wavelength polarization Mie-scattering lidar CALIOP and spectroradiometer MODIS and succeeded in revealing globally three-dimensional structures of the aerosol components for the first time in the world. Furthermore, we achieved constructing long-term, global aerosol dataset with more than 10 years; we compared the retrieved aerosol products with other aerosol data on aerosol optical depth and its spatial distribution measured by satellite and ground-based sensors, indicating that the our developed algorithms and its aerosol products were appropriate.
