GFASII provides precipitation data observed by satellites using Global Grid (with latitude and longitude of 0.1 degree width which is approximately 11 km in equatorial regions. GFASII conducts risk assessment by occurrence probability (return period) in each grid and updates the data hourly to show a global risk map of possible rain-related disasters about 1 hour behind time.
GFASII uses the satellite data from Japan Aerospace Exploration Agency (JAXA).
