Information from the IFNet secretariat
IDI-Japan has been developing Global
Flood Alert System (GFAS) since 2006.
The GFAS takes rainfall observation
data from multiple observation
satellites (as provided by NASA, USA) and
provides the information in
graphical form with heavy rain notice based on
probability estimate, which
supports flood forecast.
Originally, GFAS was
developed by using TRMM-3B42RT rainfall data.
Recently, JAXA has developed a
new algorithm of satellite rainfall data,
which is called "GSMaP".
with it, GFAS has been improved to utilize GSMap, which enable to
latency of rainfall data delivery and provide smaller scale
After the improvement of the new GFAS, we have added rainfall maps
60 countries and river basin maps.
We are waiting for your
participation on this project and opinions/comments
GFAS Homepage (under improving)
is an open network, purpose of the activities is to share experiences
information on flood issues.
We look forward to your active participation and
flood related information
to be shared among participants.
