PARLIAMENT QUESTION: IMPLEMENTATION OF MISSION MAUSAM

Sufficient facts gathered (>4 from Tier-1 pib.gov.in sources). Writing the study note.

1. At a Glance

Mission Mausam is a Central Sector Scheme of the Ministry of Earth Sciences (MoES) to make India "Weather-ready and Climate-smart" through next-gen observation, modelling and forecasting infrastructure. [S1]
Cabinet-approved on 11 September 2024 with outlay of ₹2,000 crore over two years (2024-26); formally launched by the PM on 14 January 2025. [S1][S2]
High-value for Prelims (numbers, HPC names, launch dates) and Mains GS-III (disaster management, S&T, climate resilience). [S2]

Recurring Parliament Questions (Lok Sabha/Rajya Sabha) on status of implementation, regional roll-out (e.g., North-East, Odisha), and radar network expansion have been answered by MoES through 2025-26, including the latest PIB release dated 23 July 2026 (PRID 2288238) on implementation status. [S3][S4]

11 September 2024: Union Cabinet approves Mission Mausam, outlay ₹2,000 crore for 2024-26. [S1]
26 September 2024: PM inaugurates High-Performance Computing (HPC) systems "ARKA" and "ARUNIKA" plus a dedicated AI/ML system, raising MoES total computing capacity to 21.91 petaflops. [S1]
14 January 2025: Formal launch of Mission Mausam by the Prime Minister. [S2]
Distinct from the earlier "Project Mausam" (Ministry of Culture, 2014), a cultural/maritime heritage initiative connecting Indian Ocean nations — frequently confused with this scheme. [S1]

Implementing Ministry: Ministry of Earth Sciences (MoES). [S2]
Nature: Central Sector Scheme. [S1]
Outlay: ₹2,000 crore over two years (2024-26). [S1]
Launch date: 14 January 2025, by the Prime Minister. [S2]
Executing agencies: India Meteorological Department (IMD), Indian Institute of Tropical Meteorology (IITM), National Centre for Medium Range Weather Forecasting (NCMRWF). [S2]
HPC systems: "ARKA" (11.77 petaflops), "ARUNIKA" (8.24 petaflops), plus dedicated AI/ML system (1.9 petaflops); total MoES capacity raised to 21.91 petaflops. [S1]
Core objective: Strengthen Earth System observations for an Earth-System-approach-based early warning system for seamless weather and climate services. [S2]

Scientific/Technological: Deployment of next-generation radars and satellites with advanced payloads; higher-resolution atmospheric observation networks; enhanced numerical weather prediction (NWP) models via new HPC/AI-ML capacity. [S1][S2]
Administrative: Implementation split across IMD (observation/forecasting), IITM (modelling research), NCMRWF (medium-range prediction) under MoES; region-specific roll-out queried in Parliament for North-East and Odisha. [S2]
Environmental: Aims to strengthen community resilience against climate change and extreme weather events (cyclones, floods, heatwaves). [S1]
Economic: ₹2,000 crore central outlay; expected downstream economic benefits via better agricultural, aviation, and disaster-preparedness forecasting. [S1]
Governance: Repeated Parliamentary scrutiny (multiple PQs on implementation, regional coverage, progress) signals ongoing accountability mechanism. [S3][S4]

26 Sep 2024: HPC systems ARKA and ARUNIKA inaugurated. [S1]
14 Jan 2025: Official launch of Mission Mausam by PM. [S2]
Multiple 2025-26 Parliament Questions answered on implementation status, North-East region coverage, Odisha-specific coverage, and radar network expansion. [S3][S4]
23 July 2026: Latest PIB release (PRID 2288238) reaffirming implementation status and mission objectives in response to a Parliament Question. [S2]

Mission Mausam launched by PM on 14 January 2025. [S2]
Cabinet approval date: 11 September 2024. [S1]
Outlay: ₹2,000 crore over two years (2024-26). [S1]
Implementing ministry: Ministry of Earth Sciences (not MoEFCC). [S2]
HPC systems named ARKA (11.77 PF) and ARUNIKA (8.24 PF). [S1]
Dedicated AI/ML computing system: 1.9 petaflops. [S1]
Total MoES computing capacity after upgrade: 21.91 petaflops. [S1]
Executing agencies: IMD, IITM, NCMRWF. [S2]
Scheme type: Central Sector Scheme. [S1]
Not to be confused with "Project Mausam" (2014, Ministry of Culture) — an Indian Ocean cultural-connectivity initiative. [S1]
Mission Mausam's overarching goal: "Weather-ready and Climate-smart" Bharat. [S2]

GS-III: Science & Technology — indigenous technology development; Disaster Management — early warning systems.
GS-II: Governance — accountability via Parliamentary questions on scheme implementation.
Possible question stems:
"Discuss the objectives of Mission Mausam and assess its significance for India's disaster preparedness." (GS-III)
"Examine how enhanced High-Performance Computing capacity strengthens India's weather and climate forecasting capabilities." (GS-III)
"Distinguish between Mission Mausam and Project Mausam, highlighting their respective objectives." (GS-I/II)

India Meteorological Department (IMD) — key executing agency for Mission Mausam.
National Disaster Management Authority (NDMA) — early warning dissemination linkage.
Project Mausam (2014) — commonly confused predecessor-sounding scheme under Ministry of Culture.
PARAM/HPC systems in India — broader context of India's supercomputing push.
Climate Change and India's NDCs — climate resilience linkage.
Digital India / AI Mission — AI/ML computing component overlaps with national AI strategy.
Cyclone/flood early warning systems — practical application of Mission Mausam outputs.

Confusing Mission Mausam (MoES, 2024-25, weather/climate tech) with Project Mausam (Ministry of Culture, 2014, Indian Ocean cultural network).
Mixing up Cabinet approval date (11 Sep 2024) with the formal launch date (14 Jan 2025).
Misattributing implementing ministry as MoEFCC instead of Ministry of Earth Sciences.
Confusing HPC system names ARKA/ARUNIKA (Mission Mausam, 2024) with earlier MoES supercomputers like "Mihir" or "Pratyush".
Assuming outlay is a permanent annual budget rather than a two-year (2024-26), ₹2,000 crore allocation.
