GPM 10th Anniversary Symposium
Unraveling precipitation from satellites

10-year achievements of Global Precipitation Measurement (GPM) mission
and prospect of future precipitation observations

19th Jul. 2024 (Fri)
13:00 - 17:30 (Doors: 12:30)
Marunouchi Hall & Conference + Online Streaming




“Era of global boiling has arrived” –––––– Last year, United Nations Secretary-General António Guterres stated. It simply states that we are now facing climate change that we have never experienced before. Some of the effects are beginning to impact our daily lives as more severe disasters such as heavy rainfall and floods.
NASA and JAXA have been operating the Core Observatory of the Global Precipitation Measurement (GPM) Mission, which can contribute to “unravel precipitation from satellite.” Dual-frequency Precipitation Radar (DPR) aboard GPM Core Observatory was developed by JAXA and NICT and has been in operation for more than 10 years after its launch in February 2014. GPM scientific achievements obtained are not only advancing the precipitation science but also contributing to the society in the field of water resource management.
In this symposium, the scientific achievements and contribution on the society will be highlighted by several invited experts in various fields. In addition, we will show prospects of future cloud precipitation observation by satellites, such as EarthCARE, PMM and AOS missions.
