Session Description Weather and climate, the ecosystem and human society in Asia are under strong influence of the monsoon. For understanding the Asian monsoon, precipitation information is essential. Recently, precipitation data derived from satellite observations have played important roles. The Global Precipitation Measurement Core Satellite (GPM CO) and has collected data already for 2 years and 8 months, since its launch in February 2014. GPM inherits a successful 17 year observation by the Tropical Rainfall Measuring Mission (TRMM). One advanced instrument on the GPM core satellite is the Dual Frequency Radar (GPM/DPR) that provides detailed information on the microphysical processes of precipitation. Simultaneous measurements of precipitation from the radars together with multi-channel microwave imagers profoundly improved our understandings of precipitation systems.

In addition, GPM has played an important role as a flying gauge to 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.

While the GPM core satellite inter-calibrates multiple satellite data to produce uniform global estimates around the globe, satellite derived precipitation data still have estimation errors depending on seasons and/or on regions. Thus ground validations of satellite precipitation in different conditions are also essential in the GPM project. Utilization of advanced satellite observations in precipitation science to improve numerical models and in assimilation studies are also important subjects.

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 in Asia.
