SHRI K C VENUGOPAL:

SHRI MITESH PATEL BAKABHAI:

Will the Minister of EARTH SCIENCES be pleased to state:

- (a) the details of the existing network of Doppler Weather Radars in the country and their geographical coverage;
- (b) whether  the  Government  is  considering  for  expanding  the  radar  network  to  enhance weather monitoring capabilities and cover underserved areas;
- (c) whether the Government has taken measures to increase the weather radars in the country for  increasing  the  accuracy  of  forecasting  system  under  Mission  Mausam,  if  so,  the details thereof;
- (d) the number of radars installed under the said mission as on 30 September, 2024, Statewise;
- (e) whether the Government is taking any steps to explore the integration of Doppler radar data into weather forecasting models for accurate and localized weather predictions; and
- (f) if so, the details thereof?

## ANSWER

## THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR MINISTRY OF SCIENCE AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

- (a) Currently, 39 Doppler Weather Radars (DWRs) are installed at various locations across the country.The S-band radar provides a radial coverage of 400 km, whereas C-band and X-band provide 250 km and 100 km, respectively. The State and location-wise details are given in Annexure-1.
- (b) Yes.
- (c)-(d)  Yes.The  newly  launched  Mission  Mausam  is  intended  to  augment  the  DWRs  network across  the  country  for  complete  radar  coverage  and  to  enhance  the  accuracy  of  the weather  forecasting  system.  Mission  Mausam  was  launched  in  September  2024  and planned to install 87 more DWRs by 2026.
- (e) Yes.  DWR  data  are  being  ingested  into  numerical  weather  prediction  (NWP)  models through sophisticated data assimilation techniques for improving weather forecasts.
- (f) In recent years, with the availability of computing resources within the Ministry of Earth Sciences, NWP  modeling  systems  have  been  capable  of  utilizing  multiple  radar observations  with  higher  spatial  and  temporal  resolution  to  achieve  the  target  of producing  quality  localized  forecasts.  There  are  techniques  and  advanced  decision support systems to generate location-specific forecasts for all kinds of weather with the utilization of different inputs,including all the radar observations.
