| Session Description | Weather and climate, the ecosystem and human society are under strong influence of the monsoon. For understanding the Asian monsoon, weather-related disasters, and water resources, understanding precipitation systems is essential. Recently, precipitation data derived from satellite observations have played important roles. The Global Precipitation Measurement Core Satellite (GPM CO) has collected data already for 3 years and 8 months, since its launch in February 2014. GPM inherits a successful 17- year observation by the Tropical Rainfall Measuring Mission (TRMM). The GPM core satellite is equipped with the Dual Frequency Radar (GPM/DPR) and multi-channel microwave imagers (GMI), providing detailed information on the microphysical processes of precipitation for 65N-65S range which covers 91% of the earth surface. GPM has played an important role as a flying gauge to X-calibrate microwave radiometers in space for improvement of near real time global precipitation map products, such as, the Global Satellite Mapping of Precipitation (GSMaP) and the Integrated Multi-satellitE Retrievals for GPM (IMERG). These global precipitation map products have been operationally used for weather forecasting, flood warning, river control, etc. For better qualities of satellite derived precipitation information for science and applications, ground validations are also essential. Various ground validation activities have been going on. Comprehensive studies of global precipitation characteristics, assimilation studies utilizing various types of numerical models, evaluation of energy budget of climate models with GPM-derived latent heating, evaluation of cloud microphysics of cloud resolving models with satellite data are now ongoing. This session solicits studies on following topics: 1. Science of precipitation systems utilizing satellite and radar data. 2. Ground validation of satellite precipitation data. 3. Applications of satellite precipitation data including numerical models. |
