ISRO inaugurates S–Band Polarimetry Doppler Weather Radar

Indian Space Research Organisation (ISRO) has inaugurated S–Band Polarimetry Doppler Weather Radar (DWR) at Satish Dhawan Space Centre in Sriharikota spaceport, Andhra Pradesh.

• It will be used for observation of weather system up to a range of 500 km and also for early warning of severe weather events.

About the Doppler Weather Radar (DWR):

• The radar has been indigenously developed by Bharat Electronics Ltd (BEL), Bengaluru under ToT (Training of Trainers) from ISRO.
• It is the seventh radar of such type manufactured in the country under "Make in India".
• It will provide advanced information, enhances lead-time essential for saving lives and property in event of natural disaster associated with severe weather.
• It will also provide detailed information on storm's internal wind flow and structure as compared to conventional radars which are only able to track and predict cyclones.
• Polarimetric capability of this radar will significantly help to improve accuracy of rainfall estimation leading to accurate and timely flash flood warnings. 
• With its help, severity of weather systems can be quantitatively estimated and more precise advanced warnings can be generated for saving human lives and property.
