抄録: | This study develops an algorithm to retrieve the effective particle radius of thick water clouds from geostationary meteorological satellites, Multi-functional Transport Satellite-2 (MTSAT-2) and Fengyun-2E (FY-2E). At first, the retrieval developed for Advanced Very High Resolution Radiometer (AVHRR) boarded on the NOAA sun-synchronous platforms is adapted to MTSAT-2 and FY-2E data to estimate the cloud effective radius. As a result, conflicting estimate values are showed between MTSAT-2 and FY-2E. Then, some changes and improvements are made to the original method to establish accurate algorithm. A good correlation is confirmed between the effective radius derived from MTSAT-2 and those from FY-2E after carefully considering response functions of each imager and scattering properties of clouds. The validity of this procedure is confirmed by comparing the results from MODerate resolution Imaging Spectrometer (MODIS) observations. Geostationary satellites enable high temporal resolution and global scale observations of the effective radius compared to the conventional sun-synchronous orbital satellite observations. |
