PARLIAMENT QUESTION: STATUS OF IMPLEMENTATION OF MISSION MAUSAM
1. At a Glance
- Mission Mausam is a Ministry of Earth Sciences (MoES) flagship to make India "weather-ready and climate-smart" through next-gen forecasting, observation, modelling and AI/ML services [S1][S2].
- Cabinet-approved outlay of ₹2,000 crore over two years (FY 2024-25 & 2025-26) with implementation phased till 2031 [S2][S4].
- UPSC relevance: tests GS-III (S&T, disaster management) overlap with climate adaptation, SDG-13, and India's "Vishwa Bandhu" weather diplomacy.
2. Why in the News
- Parliament Question reply (12 March 2026) by Ministry of Earth Sciences in Lok Sabha detailing status of implementation — confirmed commissioning of HPC systems and quantified forecast-accuracy gains [S1].
- PM-inaugurated HPC systems ARKA & ARUNIKA on 26 Sept 2024; mission formally launched by PM on 14 Jan 2025 (IMD's 150th Foundation Day) [S1][S5].
3. Background & Evolution
- 11 Sept 2024 — Union Cabinet approves Mission Mausam, outlay ₹2,000 cr / 2 yrs [S2].
- 26 Sept 2024 — PM inaugurates HPC systems "ARKA" at IITM Pune and "ARUNIKA" at NCMRWF Noida [S1].
- 14 Jan 2025 — PM launches Mission Mausam & releases IMD Vision-2047 at IMD's sesquicentennial [S5].
- 12 Mar 2026 — Implementation status placed before Parliament [S1].
- Predecessor / parallel: Monsoon Mission (2012), High Performance Computing System (HPCS) Pratyush & Mihir (2018), IMD Modernisation Phase-III.
4. Core Static Facts
- Nodal Ministry: Ministry of Earth Sciences (MoES) — NOT MoEFCC [S2].
- Lead implementing institutes (3): India Meteorological Department (IMD), Indian Institute of Tropical Meteorology (IITM, Pune), National Centre for Medium-Range Weather Forecasting (NCMRWF, Noida) [S2].
- Outlay: ₹2,000 crore over two years (Phase-I FY25 & FY26); phased rollout up to 2031 [S2][S4].
- HPC capacity post-commissioning: ARKA — 11.77 petaflops (IITM Pune); ARUNIKA — 8.24 petaflops (NCMRWF Noida); dedicated AI/ML system — 1.9 petaflops; total MoES HPC = 21.91 petaflops [S1].
- Beneficiary sectors: agriculture, disaster management, defence, aviation, water resources, power, tourism, shipping, transport, energy, health [S2].
- Key planned assets: expansion of Doppler Weather Radar network, wind profilers, radiosondes, ocean buoys, high-altitude balloons, mesonet observatories, urban testbeds, Cloud Chamber at IITM Pune (weather modification R&D) [S4].
5. Multi-Dimensional Analysis
Scientific / Technological - Quantum jump in compute (≈3× over Pratyush+Mihir's 6.8 PF) enables higher-resolution global & regional models, ensemble forecasting, and AI/ML nowcasting [S1]. - IMD reports 30-40% improvement in severe-weather forecast accuracy over the past decade; significant leap in tropical cyclone track/intensity forecast in 2021-25 vs 2016-20 [S1][S3].
Administrative - Three-institute consortium model (IMD-IITM-NCMRWF) under single mission to avoid silos; phased till 2031 with annual milestones [S1][S2].
Environmental / Disaster Management - Directly feeds NDMA's CAP (Common Alerting Protocol) early-warning ecosystem; supports India's commitment to UN "Early Warnings for All" by 2027 [S2].
Economic - Weather-sensitive sectors (agri, power, aviation, shipping) account for >50% of GDP; finer panchayat-level forecasts cut crop losses & power-grid risk [S2].
Geopolitical / Strategic - Mission supports India's role as regional weather services provider under WMO for South Asia & IOR; bolsters "Vishwa Bandhu" climate diplomacy.
6. Recent Developments (12-18 months)
- 11 Sept 2024 — Cabinet approval [S2].
- 26 Sept 2024 — ARKA & ARUNIKA HPC commissioned by PM [S1].
- 14 Jan 2025 — Mission Mausam formally launched on IMD's 150th Foundation Day; IMD Vision-2047 released [S5].
- 12 Mar 2026 — Lok Sabha Q&A: HPC operational, cyclone forecast skill improved 2021-25 vs 2016-20 [S1].
7. Prelims Hooks
- Mission Mausam approved by Union Cabinet on 11 September 2024 [S2].
- Total outlay: ₹2,000 crore over 2 years [S2].
- Nodal ministry: Ministry of Earth Sciences (not MoEFCC, not MoST) [S2].
- Three implementing institutes: IMD, IITM-Pune, NCMRWF-Noida [S2].
- HPC "ARKA" sits at IITM Pune (11.77 PF); "ARUNIKA" at NCMRWF Noida (8.24 PF) [S1].
- Dedicated AI/ML HPC = 1.9 petaflops; total MoES compute = 21.91 petaflops [S1].
- HPC inaugurated on 26 September 2024 by PM (video-conferencing) [S1].
- Mission launched alongside IMD Vision-2047 on 14 January 2025 (IMD's 150th year) [S5].
- Severe-weather forecast accuracy improved 30-40% over past decade [S3].
- Cloud Chamber for weather modification research is being set up at IITM Pune [S4].
- Implementation phased till 2031 [S3].
8. Mains Relevance
- GS-III: "Science & Technology — indigenization & developments"; "Disaster management"; "Climate change."
- GS-II: "Government policies/interventions" (welfare via early-warning).
- Likely stems: 1. "Mission Mausam marks a paradigm shift from forecasting to weather management. Discuss its components and challenges." (15M) 2. "Examine the role of high-performance computing and AI/ML in transforming India's weather services." (10M) 3. "How does Mission Mausam strengthen India's disaster-preparedness architecture in the context of the UN 'Early Warnings for All' initiative?" (15M)

10. Common Errors / Trap Areas
- Wrong ministry: it is MoES, not MoEFCC or DST.
- Wrong outlay period: ₹2,000 cr is for 2 years, not 5; total mission phased till 2031.
- Mixing HPCs: ARKA is at Pune (IITM), ARUNIKA at Noida (NCMRWF) — easy to swap.
- Confusing with Monsoon Mission or National Supercomputing Mission (PARAM Rudra) — different ministries (MoES vs MeitY/DST).
- Launch dates: Cabinet approval (11 Sept 2024) ≠ PM launch (14 Jan 2025) ≠ HPC inauguration (26 Sept 2024).
