## ANSWER

## THE MINISTER OF EARTH SCIENCES (SHRI KIREN RIJIJU)

- (a) At present India Meteorological Department (IMD) is operating 37 numbers of Doppler Weather Radars (DWRs) across the country, which comprises of 22 S-Band DWRs, 4 CBand DWRs and 11 X-Band DWRs. The details of the radars are given in Annexure.
- (b) The  DWRs  are  used  to  monitor  thunderstorms,  tropical  cyclones  and  other  severe weather events. The radar data products such as reflectivity and the radial velocity  are assimilated in various numerical models for generating operational forecasts at different temporal  and  spatial  resolutions.  The  assimilation  of  the  radar  products  improves  the model initial conditions and thereby the forecasts. These products are also used for the nowcast and very short  range  weather forecasts,  up  to  12  hours,  issued  by  IMD  using High resolution Rapid Refresh (HRRR) regional model.
- (c) Another 20 more DWRs are at different stage of commissioning in a phased manner by IMD to bring the entire country under the radar coverage.
