The cloud microphysical properties retrieved from MODIS sub-sampling radiance dataset (MOD02SSH) over the extended GAME region are shown in this paper. The spatial distributions and temporal variations of the cloud optical thickness (τ_c) and effective particle radius (r_e), are important observation targets to understand the role of clouds in the radiation budget estimations, especially in the cloud-aerosol interaction studies, because they will have information of cloud growth process. Thus, the wide-area and relatively high-temporal observations of the cloud properties are necessary. The most passed researches that retrieved near-global distributions of the cloud properties, used the reduced data volume satellite radiance subset, such as the globally map-projected radiances dataset at the discretized degrees in latitude and longitude (e.g. 0.5 degrees) or narrow-swath (around nadir) radiance subset. In fact, these subsets reduced the computing time but unexpectedly reduced the observation samplings. In this study, we used MODIS 5-km subsampling radiance subsets (MOD02SSH) for the retrievals. The MOD02SSH conserves scene texture with moderately reduced data volume of 1/25 from original MODIS scene, so that they will be suitable for the more precise estimations of τ_c and r_e over synoptic to global scale. We retrieved τ_c and r_e from one-month MOD02SSH over the extended GAME region (60E-180E longitude and 20S to 60N latitude) in July 2004. In the obtained τ_c versus r_e scatter plots, we found interesting features that will be explained as the cloud properties under the pristine and polluted environments in the region. The non-hydrostatic spectral microphysics cloud model simulates these phenomena well. In the presentation, we will discuss about the MODIS radiance dataset for the cloud analysis, retrieval algorithm, then show the typical and interesting features appeared in observed τ_c - r_e scatter plots over the extended GAME regions.
