| Session Description | Weather and climate in Asia is thoroughly affected by monsoon. Precipitation data is one of the essential variables to be observed for realizing the Asian monsoon. Satellite precipitation data have been accumulated more than 20 years. Especially, the TRMM (Tropical Rainfall Measuring Mission) satellite observation with information of three dimensional structure of rainfall pioneered a new research discipline called precipitation system climatology. Seasonal change, diurnal cycle of precipitation, and their difference region by region etc., have been known by analyzing TRMM data. Satellite derived precipitation data still yet have estimation errors depending on season and/or region. To obtain more accurate satellite data, it is desirable that satellite data will be compared with ground observation data in different conditions for validation. On the other hand, satellite precipitation data is can be applied for real applications such as weather forecast, utilization in flood early warning system and so on. In this background, the future satellite project called GPM (Global Precipitation Measurement) is now planned for launch in 2013. Thus in this session, we will discuss on 1. new knowledge on precipitation science obtained by satellite data 2. ground validation of satellite precipitation data 3. applications of satellite precipitation data in Asia. |
