Research Abstract

The algorithm used to retrieve the cloud effective particle radius from the 3.7m band was adapted to the corresponding channel of the Japanese Advanced Meteorological Imager (JAMI) own onboard the Multi-functional Transport Satellite (MTSAT) geostationary platform. Snapshot comparisons with spatially well resolved retrievals from the MODerate resolution Imaging Spectrometer (MODIS) instruments own on the Terra polar platforms show qualitative agreement with MTSAT retrievals. The results of analyzing daytime variation across from the Eastern Asia to the north the Northwest Pacific Ocean show that not only the effective particle radius is smaller in continental clouds than maritime clouds but also daytime amplitude of the effective particle radius is greater in continental clouds than maritime clouds in which the effective particle radius value is approximately constant.
