ISRO is working on
systems to forecast the natural disasters that could be used as input by
States/ disaster management agencies.
ISRO is carrying out studies to facilitate best use of the satellite
derived information to develop methodologies for forecasting the natural
disasters. Some of such methodologies developed include:
i. Cyclone formation, track and Intensity: ISRO has developed
methodologies for forecasting the cyclone formation, it’s track and
intensity using satellite based observation. The methodology developed
has been transferred to India meteorological Department (IMD) who is
mandated for cyclone forecast.
ii. Flood Early Warning System: The North Eastern Space Applications
Centre (NESAC) of ISRO has developed the Flood Early Warning System
(FLEWS) as a Research & Development (R&D) project in Assam State in
association with Assam State Disaster Management Authority (ASDMA). The
FLEWS model is being used in all 25 flood prone districts of Assam.
Another model for forecasting floods in Godavari floodplains in Andhra
Pradesh is developed by National Remote Sensing Centre (NRSC) of ISRO.
The methodology is being used by Central Water Commission (CWC). ISRO is
developing similar systems for Krishna, Brahmani-Baitarani, Ghagra,
Gandak, and Kosi rivers.
iii. Heavy Rainfall/ cloud burst alerts: Space Applications Centre (SAC)
of ISRO has developed a model, for heavy rainfall / cloud burst alerts,
which is being experimentally carried out for Indian region. The
information is made available on ISRO’s MOSDAC (Meteorological &
Oceanographic Satellite Data Archival Centre) website.
iv. Rainfall triggered landslide alerts for the Uttarakhand Region: An
experimental early warning system for rainfall triggered landslides is
developed for use along the pilgrimage route corridors leading to
Gangotri, Badrinath and Kedarnath as well as along the Pithoragarh-Malpa
route in Uttarakhand. The forewarning is generated based on the
statistical relation between the terrain (geological, morphological) and
temporal (primarily long term rainfall events) factors.
v. Extreme weather events: ISRO has developed experimental methodologies
for early warning extreme weather events such as heat wave using
numerical weather predictions. The information derived is being made
available on the MOSDAC website.
ISRO has realised two satellite missions, Viz., MeghaTropiques (launched
in Oct 2011) and SARAL (launched in Feb 2013), in collaboration with
French National Space Agency (CNES). Presently, ISRO is working with
National Aeronautics and Space Administration (NASA), USA towards joint
realisation of a satellite mission, namely, ‘NASA-ISRO Synthetic
Aperture Radar (NISAR), to be launched by 2020-21 timeframe. The fund
allocation for MeghaTropiques is Rs. 81.6 Crores, SARAL is Rs. 73.75
Crores and for NISAR is Rs. 513 Crores.
