What is Ministry of Earth Sciences (MoES)

About Ministry of Earth Sciences

The Ministry of Earth Sciences (MoES) serves as India’s nodal authority for integrating scientific research and operational services across the atmosphere, ocean, cryosphere, geosphere, and biosphere. Its core mandate encompasses delivering critical weather forecasts, monsoon predictions, cyclone warnings, and seismological monitoring, while simultaneously advancing the nation’s Blue Economy and deep-ocean exploration initiatives.

Key Institutions and Jurisdictions

1. India Meteorological Department (IMD): Responsible for operational weather forecasting, monsoon tracking, and severe weather/cyclone alerts. Celebrated 150 years in 2025 with the release of IMD Vision-2047.
2. Indian Institute of Tropical Meteorology (IITM, Pune): Specialized in advanced climate modeling, monsoon research, and cloud-aerosol atmospheric studies.
3. Indian National Centre for Ocean Information Services (INCOIS, Hyderabad): Houses the Indian Tsunami Early Warning Centre; issues ocean state forecasts and Potential Fishing Zone (PFZ) advisories.
4. National Institute of Ocean Technology (NIOT, Chennai): Focuses on indigenous ocean engineering, marine instrumentation, and deep-sea exploration systems.
5. National Centre for Polar and Ocean Research (NCPOR, Goa): Nodal agency for India’s scientific expeditions to the Antarctic, Arctic, Southern Ocean, and Himalayan cryosphere.
6. National Centre for Medium Range Weather Forecasting (NCMRWF, Noida): Specializes in medium-range numerical weather prediction and dynamic modeling.
7. National Centre for Earth Science Studies (NCESS, Thiruvananthapuram): Conducts foundational geoscience research and coastal process monitoring.

Flagship Initiatives and Missions

1. Mission Mausam
   1. Objective: A ₹2,000 crore initiative to make India weather-ready and climate-smart using AI/ML, next-generation radars, and high-performance computing.
   1. Implementation: Jointly executed by IMD, IITM, and NCMRWF.
   1. Recent Update: Expanded in May 2026 via an IITM mandate to utilize a comprehensive “health system approach” for scaling weather services over a five-year rollout.
2. Deep Ocean Mission
   1. Objective: A ₹4,077 crore mission to sustainably harness ocean resources, focusing on polymetallic nodules, marine biodiversity, and Ocean Thermal Energy Conversion (OTEC).
   1. Samudrayaan Project: The manned deep-ocean exploration component featuring Matsya-6000, a titanium-alloy submersible indigenously developed by NIOT to carry three personnel to a depth of 6,000 meters.

Conclusion

The Ministry of Earth Sciences is integral to India’s climate resilience and strategic maritime objectives. Through advanced meteorological forecasting and pioneering initiatives like the Deep Ocean Mission and Mission Mausam, it ensures robust disaster preparedness while securing the nation’s sustainable Blue Economy.
