Chennai, May 1 (UNI) Indian Space Research Organisation (ISRO) today signed a Memorandum of Understanding with Snow and Avalanche Study Establishment (SASE) of the Defence Research and Development Organisation (DRDO) for installation of two Doppler Weather Radars (DWR) in the Himalayan region for climate studies.
ISRO has indigenously developed the technology of DWR and transferred it to Bharat Electronics Ltd for the production of these radars, a release said here.
The DWR operates in S band and is capable of monitoring clouds, precipitation systems and winds, over large areas of more than 400 km from the radar location. DWR has the unique capability to continuously track and predict fast evolving weather systems such as thunderstorms, cyclones and cloud bursts.
The first such indigenous radar was operating at Sriharikota since April 2004. The mark II version of DWR, which was under production was a state of the art system with performance comparable with radars available elsewhere.
As per the MoU, two DWR, with advanced polarimetric capability, would be established in the Himalayan region to monitor critical climate parameters, including snowfall, and help in improved weather forecasts for high altitude operations.
The data from DWR would be useful for the study of monsoon dynamics, avalanche prediction, detection of clear air turbulence and tracking of cloud burst, hailstorm and other severe weather events. In view of the global warming scenario, it was of paramount importance to monitor the highly sensitive and climatically unique Himalayan terrain.
ISRO was also installing two DWRs in the North East region of India to support disaster management by aiding the early warning of floods, landslides and other weather events.
The Indian Meteorological Department has already procured two such radars from BEL for installation at Kochi and Bhuj for cyclone monitoring, the release added.
