About Earth Monitoring and Disaster Warning Working Group 
Fo improve methods of taking prompt actions against regional 
disasters and to provide real time warning to local habitants for 
an advanced evacuation and anticipation, Wild Fire Board of 
Forum was formed at the IWS98/APAN meeting in March 
1998. 
By expanding its focus onto tropical cyclones, torrential rain 
and flooding, the Earth Monitoring and Disaster Warning 
Working Group was proposed at the APAN Committee with a 
draft charter, during the APAN Seoul meeting in July 1998, 
and an approval on formation of the WG was given. 
Collaboration with earth observation missions and 
IWS 9 9/Osaka 
The WG established ties with earth observation missions of 
major space agencies, NASA, NASDA, ESA, NOAA and DLR 
for disaster management. 
In the two organized sessions of APAN within the Internet 
Workshop99, held at Osaka University on 18 February 1999, 
fire detection technologies and their applications were 
presented in the “Earth Monitoring I” and TRMM mission and 
applications in “Earth Monitoring II” respectively (APAN- 
sessions, 1999). 
Organized session 1: “Earth Monitoring I” 
Remote sensing fire detection system and future network 
development (Sawada, 1999) 
Fast delivery products for monitoring the Earth with the 
European Remote Sensing Satellite II (Buongiomo, 1999) 
Fire detection with Defense Meteorological Satellite 
Program(DMSP) Operational Linescan Sensor(OLS)Data 
(Nelson, 1999) 
Forest Fire In INDONESIA Impacts Factors and Evaluation 
(Aziz, 1999) 
Organized session 2: “Earth Monitoring A” 
TRMM Real time data production, transfer and plans (Stocker, 
1999) 
TRMM visualization (Sobue, 1999) 
Detection of lightning by LIS/TRMM and its application 
(Kawasaki, 1999) 
Taking the discussion and comments raised from the sessions 
into the consideration on earth observation and disaster 
network, the status report and the future actions of the Earth 
Monitoring WG were presented by the chair (Fujita, 1999a). 
The German Space Agency (DLR) is developing a dedicated 
sensors for fire detection, those sensors will be loaded in a 
small satellite experiment (BIRD) and in the International 
Space Station. A meeting held at DLR Berlin, the WG and 
DLR’sDBIRD/FOCUS team has agreed to distribute a call for 
interest via APAN to potential users of these new Fire 
Prototype Data Products of BIRD/FOCUS. 
Real time TRMM/DMSP networking for disaster management 
Tropical Rainfall Mapping Mission (TRMM) was developed to 
make precise rainfall estimation in the tropics region between 
35 degrees north and south. The real time TRMM data is 
available at NASA Goddard Space Flight Center (GSFC) and 
the WG applied the continuous access to the data for 
distribution to collaborating institutes and product 
dissemination to users through APAN.
