Global Flood Alert System ver.2 (GFAS-II) released
  12th June 2015 / IFNet secretariat




IDI-Japan has been operating gGlobal Flood Alert System (GFAS)h on the following web site
since April 2006.
[for PC] http://gfas.internationalfloodnetwork.org/gfas-web/

GFAS provides a global flood risk map which shows precipitation return period calculated from
satellite precipitation data of TRMM(*1).
GFASfs horizontal resolution is about 25 km and we update its data every 24 hours.

On the other hand, JAXA has been delivering another satellite-based precipitation data, GSMaP
(Global Satellite Mapping of Precipitation *2). Its horizontal resolution is about 10km and it is
updated every hour.

With 2016 being the fifteenth year since the data collection of GSMaP was started, IDI-Japan
began to develop the next version of GFAS which uses GSMaP data. And recently, we opened
the following web sites as the trial version for GFAS-II.
