ANSWER
THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR
MINISTRY OF SCIENCE AND TECHNOLOGY
AND EARTH SCIENCES
(DR. JITENDRA SINGH)
(a) Currently, 48 Doppler Weather Radars (DWRs) are in operation across India, including
one X-Band DWR commissioned at Jorhat, Assam, on 19.01.2026. The number of weather
radars installed across the country till date is given in Annexure -I.
(b) Currently, two Doppler Weather Radars are operational in the State of Kerala; one S-Band
DWR at IMD, Kochi, commissioned in July 2017 and upgraded in 2025, and a C-Band
DWR at ISRO, Thiruvananthapuram, commissioned in August 2016.
(c) & (d) At present, most of the areas of the State of Kerala is covered by the Radar Network,
including the S-Band DWR at IMD Kochi, the C-Band DWR at ISRO
Thiruvananthapuram, and the newly installed C-Band DWR at IMD Mangalore.
However, there are some gaps in the radar coverage of the current network of DWRs
mainly over the coastal and hilly regions of Kerala, including Wayanad and Idukki.
Additionally, the Ministry of Earth Sciences (MoES) launched Mission Mausam with the
goal of making India a "Weather-ready and Climate-smart" nation, aiming to mitigate the
impacts of climate change and extreme weather events.
(e) The S-Band DWR at Kochi was upgraded in 2025 to enhance forecasting capability, which
is highly useful for both monsoonal heavy rainfall warning and cyclone tracking for coastal
districts. The location for the installation of a new DWR in Wayanad has also been
identified.Annexure-I List of 48 Doppler Weather Radars installed so far in the country.
