| 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.
