Photopolarimetric observations of atmospheric aerosols from space and/or sea surface

This work presents spatial and temporal change of optical properties of aerosols over Japan and Western Australia. The measurements by a portable multi-spectral polarimeter (PSR-1000) from 1997 to 2000 provide the optical thickness of aerosols and the A˚ngstro¨m exponent. For comparison, the same aerosol parameters are derived from the satellite data, e.g. ADEOS / POLDER and/or SeaWiFS data. It is shown that the obtained results from the space-based data are validated with the results from the ground measurements on a local scale, and the retrieved aerosol characteristics exhibit each intrinsic feature for each region.
