**Executive Summary**
The Ministry of Earth Sciences reported on the strengthening of radar infrastructure in Kerala, specifically the deployment and upgrade of Doppler Weather Radars (DWRs) to improve weather forecasting and disaster preparedness. As of February 12, 2026, there are 48 DWRs operational across India. The document highlights existing radar coverage in Kerala, identifies gaps, and notes the Ministry's "Mission Mausam" initiative to make India "Weather-ready and Climate-smart."
**Key Points / Main Content**
* **National Radar Infrastructure:**
* 48 Doppler Weather Radars (DWRs) are currently operational across India.
* One X-Band DWR was commissioned in Jorhat, Assam, on 19.01.2026.
* Annexure-I lists all 48 DWRs installed across the country.
* **Kerala Radar Infrastructure:**
* Two Doppler Weather Radars are operational in Kerala: an 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).
* Most 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.
* There are coverage gaps in coastal and hilly regions, including Wayanad and Idukki.
* The location for a new DWR in Wayanad has been identified.
* **Mission Mausam:**
* Launched by the Ministry of Earth Sciences to make India a "Weather-ready and Climate-smart" nation.
* Aims to mitigate the impacts of climate change and extreme weather events.
* **Upgrade and Forecasting:**
* The S-Band DWR at Kochi was upgraded in 2025 to enhance forecasting.
* This is highly useful for monsoonal heavy rainfall warning and cyclone tracking for coastal districts.
**Impact Analysis**
**Stakeholder**: *Coastal Districts of Kerala*
**Impact:** Improved weather forecasting capabilities, particularly for monsoonal heavy rainfall and cyclone tracking.
**Action Required**: Utilize improved forecasting data for disaster preparedness and mitigation efforts.
**Stakeholder:** *Residents of Kerala (Wayanad and Idukki)*
**Impact:** Reduced weather coverage in areas surrounding Wayanad and Idukki. Plans to install new DWR in Wayanad have been identified.
**Action Required:** No current action required.
**Stakeholder:** *Ministry of Earth Sciences (MoES)*
**Impact:** Responsible for the successful implementation of Mission Mausam and the expansion of radar infrastructure.
**Action Required:** Continue implementing Mission Mausam and install a new DWR in Wayanad.

PARLIAMENT QUESTION: STRENGTHEING
RADAR INFRASTRUCTURE IN KERALA
Posted On: 12 FEB 2026 12:54PM by PIB Delhi
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.
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.
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.
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.
This information was submitted by Union Minister of State (Independent Charge) for Earth Sciences Dr.
Jitendra Singh in Rajya Sabha on 12th February 2026.
