India losing ability to build its own instruments: climate science report

📌 Summary:

• Leading Indian climate scientists, in a new report, have warned that India has almost lost the ability to build its own scientific instruments, leaving climate observations dependent on imported equipment that often runs uncalibrated for years
• Consequence: "incorrect data being reported in national and international journals, often leading to questions on the credibility of Indian science" — undermines India's standing in global climate research and IPCC contributions
• Report calls for long-term studies on the climate impact of "uncontrolled" growth of renewable-energy installations — effects of large solar and wind plants on regional climate (heat islands, wind-pattern disruption, microclimate change) remain "poorly understood"
• Highlights a structural weakness in Atmanirbhar Bharat in science: while India is a major user of climate models, it is increasingly a price-taker for sensors, radiosondes, lidars, ocean buoys, satellite payloads
• Implication for policy: under-invested instrument-making ecosystem hurts S&T self-reliance; affects Mission Mausam, monsoon forecasting accuracy, ocean observation (Indian Argo) and clean-energy planning

🎯 UPSC Relevance: GS3 — Science & Technology: Indigenisation, R&D capacity, instrument-manufacturing ecosystem; GS3 Environment — Climate research and data credibility; impact of renewables on local climate.

📝 Prelims Facts:

• Key Indian climate-science institutions: IITM Pune (Indian Institute of Tropical Meteorology), NCMRWF (National Centre for Medium Range Weather Forecasting), IMD, NCPOR Goa, INCOIS Hyderabad — all under Ministry of Earth Sciences (MoES)
• Mission Mausam: launched September 2024, ₹2,000 crore (FY 2024-26) to expand observational network, supercomputing, weather modification capability
• IPCC = Intergovernmental Panel on Climate Change (UNEP + WMO); India is a member
• India's renewable-energy installed capacity exceeded 200 GW in 2025; target 500 GW non-fossil by 2030 (PIK Paris commitment)
• Argo programme = global float-based ocean-observation network (India participates via INCOIS)

🔑 Key Term: Instrument Calibration — The process of periodically comparing a measurement device's readings against a reference standard to correct drift; uncalibrated scientific instruments produce systematically biased data that, when published, can erode the credibility of an entire research community.
