Sentinel Asia consists of
104 JPT members incl.
89 agencies from 27 countries and 15 international organizations
(as of Apr 2017) and ADRC members
Platform to discuss cross‐cutting issues
Sentinel Asia is a voluntary initiative by a collaboration between space agencies and disaster management agencies, applying Remote Sensingand Web‐GIS technologies to assist disaster management in the Asia‐Pacific region.

GSMaP observing harricane Patricia and Olaf and Typhoon Champi: 2015/10/20~2015/10/24(hourly animation)
• For climate phonomena that changes rapidly, frequent observations are very much needed.
• Global precipitation map integrating the data from GPM core observatory, microwaveradiometers/sounders, and infrared radiometers of geostationary satellites
JAXA Global Rainfall Watch (4‐hr delay) : http://sharaku.eorc.jaxa.jp/GSMaPJAXA Realtime Rainfall Watch (Himawari‐area): http://sharaku.eorc.jaxa.jp/GSMaP_NOW
We have started to provide GSMaP_NOW over the area of Himawari‐8!
• It provides precipitation data in an hour after observation
• We improved the data latecy from GSMaP’s 4 hours to “quasi-real-time”

Our Visions
Looking forward to further fruitful collaboration with our partners in Asia and the Pacific.
1. JAXA aims that the earth observation system wouldbecome the Space-based Infrastructure as an essential partfor our daily life.
2. Space-based Infrastructure should be utilized for specificaction and its decision making as a step ahead of theobservation and understanding of its phenomenon
3. Space agencies should lead establishment of space-basedinfrastructure to innovate new systems, new value, and/ornew business in a wide range of areas.
