Land Shortage Stalls India's National Weather Sensor Network Expansion
Implementation of the WINDS project faces critical delays due to strict ground-level installation requirements.
1WINDS Project Stagnation
The Weather Information Network and Data System project is currently failing to meet its deployment targets. Over 96% of the planned 50,500 sensors remain uninstalled across various Indian states. This initiative, managed by the Mahalanobis National Crop Forecast Centre, is now at least one year behind its original completion schedule.
2Scope of Sensor Deployment
The project involves three private partners tasked with installing 1,197 automatic weather stations and 49,313 automatic rain gauges. These sensors are designed to provide hyper-local data for the Pradhan Mantri Fasal Bima Yojana insurance scheme. Currently, only 113 weather stations and 1,730 rain gauges have been successfully deployed nationwide.
3The Siting Bottleneck
Implementation partners report that site selection is the primary obstacle to progress. In Uttar Pradesh alone, 16,478 out of 27,644 proposed sites were rejected. Similar rejection rates appear in Odisha and Kerala. Issues include duplicate site approvals, pending administrative clearances, and a general lack of suitable land available for sensor placement.
4Retrospective Guideline Changes
Private contractors claim that a 2025 amendment to the project manual created significant friction. While the 2023 guidelines permitted rooftop installations for rain gauges, the updated rules retroactively capped these at 10% to 15%. This shift forced companies to scramble for ground-level space, which was not accounted for in initial planning.
5IMD Technical Justification
The India Meteorological Department maintains that ground-level placement is essential for data accuracy. Officials argue that rooftop measurements suffer from evaporation and height-related inconsistencies. Adhering to World Meteorological Organisation standards, the agency insists that sensors must be on the ground to ensure standardized, reliable data for national agricultural forecasting.
6Strict Regulatory Requirements
The 2025 amendment mandates that rooftop installations now require a formal justification note from states. Even in flood-prone or landslide-prone regions, the 15% cap remains a firm constraint. This regulatory shift requires prior approval from the WINDS Committee, adding layers of bureaucratic complexity to an already struggling infrastructure rollout process.
7Data Integrity vs Speed
Director General M. Mohapatra emphasized that the IMD acts only as a technical partner. He stated that consistent ground-based networks are vital for accurate insurance payouts and crop forecasting. While the ministry seeks to maintain high scientific standards, the current land acquisition challenges threaten the viability of the entire network.
8Future Project Outlook
The project remains in a state of uncertainty as the Mahalanobis National Crop Forecast Centre has not responded to inquiries regarding the delays. With the vast majority of sensors still pending, the government must resolve the land availability crisis to meet its objective of providing hyper-local weather data for farmers.
