[ABSTRACT] We present a case study in which aerosol optical properties over Chiba land area are derived from Landsat/TM visible channel data. First, the surface albedo value is obtained for each pixel from the atmospherically corrected TM image (January 14, 1999) with relatively small aerosol optical thickness (AOT). After the correction using the 6S code, this ‘clean’ image provides the “ρ map” that can be used as a reference. Second, a test image (December 13, 1998) with relatively large AOT is compared with the clean image to study the aerosol optical properties. By changing the aerosol particle radius, this test image is also subjected to the atmospheric correction, and the resulting surface albedo is compared with the ρ map. The parameter optimization is carried out on the basis of the standard WMO-WCP55 continental aerosol model, with the contribution from WMO-WCP112 water-soluble particles. The aerosol particle radius over Chiba area on December 13, 1998 is found to be 4.0×10^-3 μm, slightly smaller than the radius of the standard water-soluble particles.
