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.

.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.

DWR data are being ingested into numerical weather prediction (NWP) models through sophisticated data assimilation techniques for improving weather forecasts.

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.
