Mission Mausam aims to make India a “weather-ready and climate-smart” nation by strengthening weather and climate observation, forecasting, modelling, research, and early-warning systems. The mission is designed to improve the accuracy and timeliness of weather information while helping communities and different sectors prepare for extreme weather and climate-related risks.
The Union Cabinet approved Mission Mausam on 11 September 2024, with an outlay of ₹2,000 crore for two years. The Ministry of Earth Sciences (MoES) is chiefly responsible for implementing the initiative.
The mission brings together advanced observation systems, next-generation radars, satellites, high-performance computing, improved Earth-system models, artificial intelligence, machine learning, and better systems for delivering weather information to the public.
Its broader purpose is to improve India’s ability to understand and respond to weather and climate risks rather than simply predicting tomorrow’s temperature.
What Is Mission Mausam?
Mission Mausam is a central government initiative focused on improving India’s weather and climate capabilities.
The Ministry of Earth Sciences explains that tropical weather is particularly difficult to predict because of the complexity of atmospheric processes. The mission therefore seeks to improve observations, scientific understanding, numerical models, computing infrastructure, and data-driven methods.
The initiative covers several connected areas:
- Weather observation
- Weather forecasting
- Climate modelling
- Atmospheric research
- Extreme-weather warnings
- Advanced radar and satellite systems
- High-performance computing
- Artificial intelligence and machine learning
- Weather-management technologies
- Decision-support systems
- Last-mile dissemination of forecasts
Rather than treating each area separately, Mission Mausam is intended to strengthen the overall weather and climate information system.

Why Does India Need Mission Mausam?
India experiences a wide range of weather conditions because of its geography, monsoon system, coastline, mountains, deserts, plains, and rapidly growing urban areas.
Weather events can affect millions of people at the same time.
For example, heavy rainfall can disrupt roads and railways, damage crops, cause flooding, and affect urban infrastructure. Heat waves can create serious risks for public health and increase electricity demand. Cyclones can threaten coastal communities, agriculture, ports, and infrastructure.
The challenge is not simply knowing that an event may occur.
Authorities also need to know:
- Where it is likely to occur
- When it may occur
- How severe it could become
- Which communities could be affected
- How much rainfall may be expected
- How conditions may change over time
- What action should be taken
Mission Mausam is designed to improve these capabilities by strengthening the scientific and technological foundation behind weather services.
What Are the Main Objectives of Mission Mausam?
Mission Mausam has several interconnected objectives rather than one single goal.
1. Strengthen Weather Observation Systems
Accurate forecasting begins with accurate observations.
Weather scientists need information about atmospheric conditions at different locations and heights. Mission Mausam aims to improve India’s observation network by introducing and expanding advanced systems.
These include:
- Doppler Weather Radars
- Satellites with advanced instruments
- Automatic weather stations
- Wind profilers
- Radiometers
- Aerosol and atmospheric monitoring systems
- Other high-resolution observation technologies
The Ministry of Earth Sciences lists stronger, higher-resolution atmospheric observations as one of the mission’s key objectives.
Better observations can give forecasting systems more detailed information about what is happening in the atmosphere.
2. Improve Weather Forecasting Accuracy
One of the most important goals of Mission Mausam is to improve weather and climate prediction.
Weather forecasting depends on complex numerical models that process enormous quantities of atmospheric and environmental data.
Better observations combined with improved models and computing power can help scientists generate more detailed forecasts.
Mission Mausam specifically focuses on improving forecasting across different time scales, including short-term, medium-term, extended-range, and seasonal forecasting.
This can be particularly important for monsoon forecasting, which has major implications for India’s agriculture and water resources.
3. Improve Early Warnings for Extreme Weather
A forecast becomes much more valuable when people have enough time to act on it.
Mission Mausam aims to strengthen early-warning capabilities for high-impact weather events.
These can include:
- Tropical cyclones
- Heavy rainfall
- Severe thunderstorms
- Heat waves
- Cold waves
- Dust storms
- Snowfall events
- Other extreme weather conditions
The government has described the mission’s broader goal as making India “weather-ready and climate-smart” and improving early warnings to protect life and property.
For example, an earlier and more precise cyclone warning can give authorities additional time to evacuate vulnerable coastal communities and prepare emergency services.
4. Deploy Next-Generation Weather Radars
Weather radars are important tools for monitoring rainfall, thunderstorms, and other atmospheric conditions.
Mission Mausam includes the deployment of next-generation radars and expansion of India’s radar network.
In December 2024, the government stated that plans included 87 additional Doppler Weather Radars, 15 radiometers, and 15 wind profilers, with the objective of improving observations of both surface and upper-atmospheric conditions.
The mission’s implementation has since progressed further. A March 2026 update from the Ministry of Earth Sciences reported commissioning of 53 Doppler Weather Radars, along with additional observation infrastructure including radiosonde/radiowind stations, disdrometers, wind profilers, and microwave radiometers.
This demonstrates that Mission Mausam is not limited to a research concept; infrastructure deployment is a major part of its implementation.
5. Use Artificial Intelligence and Machine Learning
Modern weather forecasting produces enormous amounts of data.
Artificial intelligence and machine learning can help researchers identify patterns and relationships within complex datasets.
Mission Mausam includes the development of improved Earth-system models and data-driven methods using AI and machine learning.
AI and ML can potentially support areas such as:
- Weather prediction
- Data analysis
- Pattern recognition
- Forecast refinement
- Extreme-weather prediction
- Climate modelling
However, AI is not intended to replace atmospheric science. It can work alongside numerical weather prediction, observations, physical models, and expert analysis.
The combination of scientific understanding, computing, observations, and AI is an important part of Mission Mausam’s approach.
6. Develop High-Performance Computing Infrastructure
Weather forecasting requires enormous computational power.
Atmospheric models divide the Earth into many sections and calculate how conditions could change over time. Increasing the resolution of these models can require significantly more computing resources.
Mission Mausam therefore includes the implementation of high-performance computing (HPC) systems.
More computing power can support:
- Higher-resolution forecasting
- More complex Earth-system models
- Faster data processing
- Large-scale simulations
- Advanced AI and machine-learning applications
- Improved climate research
The relationship is straightforward: better observations provide more information, while better computing infrastructure helps scientists process that information and run increasingly sophisticated models.
7. Improve Understanding of Weather and Climate Processes
Mission Mausam is not only about building hardware.
Another major objective is improving scientific understanding of atmospheric and climate processes.
The atmosphere is highly complex. Weather is influenced by interactions between the atmosphere, oceans, land surfaces, ice, and other components of the Earth system.
Better understanding of these processes can help scientists develop more accurate models and improve predictions.
This is particularly important for phenomena such as India’s monsoon, tropical cyclones, extreme rainfall, and heat waves.
8. Develop Improved Earth System Models
Earth-system models attempt to represent interactions between different components of the planet.
Mission Mausam aims to develop improved Earth-system models and data-driven methods to strengthen prediction capabilities.
These models can help researchers study both short-term weather conditions and longer-term climate patterns.
Improved modelling can support decision-making across sectors that depend heavily on weather and climate information.
9. Improve Weather Management Technologies
Mission Mausam also includes technologies related to weather management.
Government documents have highlighted areas such as research and technologies associated with managing or intervening in phenomena such as fog, hail, and rain.
This is different from simply predicting weather.
Forecasting asks:
“What is likely to happen?”
Weather-management research explores:
“Can particular weather-related impacts be managed or influenced using appropriate scientific methods?”
Such technologies require careful research because atmospheric processes are complex and outcomes can vary depending on local conditions.
10. Deliver Weather Information to the Last Mile
Accurate forecasting is only useful if people can receive and understand it.
Mission Mausam therefore places importance on dissemination and last-mile connectivity.
The mission includes developing a state-of-the-art Decision Support System (DSS) and dissemination systems to help deliver weather information effectively.
This is especially important for people who may not regularly monitor national weather reports.
A farmer, fisherman, transport operator, municipal authority, or emergency-management team may need information specifically relevant to their location and activity.
The goal is therefore not simply to generate more data but to turn that data into useful information.
How Can Mission Mausam Help Farmers?
Agriculture is highly dependent on weather.
Farmers make decisions about:
- Sowing
- Irrigation
- Fertilizer application
- Harvesting
- Pest management
- Crop protection
Unexpected rainfall or prolonged dry periods can affect these decisions.
More accurate and localized weather information can help farmers plan operations more effectively.
For example, if heavy rainfall is forecast, a farmer may adjust irrigation or harvesting plans. If extreme heat is expected, crop-management decisions may need to change.
The government identifies agriculture and water-resource management among the sectors expected to benefit from Mission Mausam.
How Can Mission Mausam Help During Disasters?
Extreme weather can quickly become a disaster when communities do not have enough time to prepare.
Better forecasting and early-warning systems can support disaster-management agencies by providing information about potential hazards before they reach vulnerable areas.
For example:
- Observation systems detect changing atmospheric conditions.
- Forecasting models process the information.
- Scientists assess the expected weather event.
- Alerts are generated and communicated.
- Authorities prepare emergency measures.
- Communities can take protective action.
This chain demonstrates why improving only one part of the system is not enough.
Mission Mausam aims to strengthen the entire process from observation to communication.
Which Organizations Implement Mission Mausam?
Mission Mausam is primarily implemented through three Ministry of Earth Sciences institutions:
- India Meteorological Department (IMD)
- National Centre for Medium Range Weather Forecasting (NCMRWF)
- Indian Institute of Tropical Meteorology (IITM)
Other MoES institutions, along with national and international research organizations, academia, and industry partners, can also support the mission.
This collaborative structure is important because modern weather science requires expertise in atmospheric science, oceanography, computing, satellite technology, data science, engineering, and other disciplines.
What Technologies Are Used in Mission Mausam?
Mission Mausam brings together several advanced technologies rather than depending on one system.
Doppler Weather Radars
These help monitor rainfall, thunderstorms, and atmospheric movement.
Satellites
Advanced satellite instruments can provide observations across large geographical areas.
Automatic Weather Stations
These provide weather measurements from different locations.
Wind Profilers
These help monitor wind conditions at different heights in the atmosphere.
High-Performance Computers
These support complex numerical weather and climate models.
Artificial Intelligence and Machine Learning
These can help process data and develop data-driven forecasting methods.
Decision Support Systems
These help turn weather information into useful information for stakeholders and decision-makers.
Together, these technologies create a more comprehensive weather-information ecosystem.
Which Sectors Can Benefit From Mission Mausam?
The mission has applications far beyond television weather forecasts.
Government information identifies several sectors that can benefit, including:
- Agriculture
- Disaster management
- Aviation
- Shipping
- Water resources
- Energy
- Power
- Health
- Transport
- Tourism
- Defence
- Environment
- Urban planning
- Road and rail transport
- Offshore operations
For example, aviation authorities need reliable information about visibility, thunderstorms, winds, and other conditions. Shipping operations need information about storms and ocean-related weather. Electricity providers need to understand conditions that can affect energy demand and renewable-energy generation.
Mission Mausam vs. Project Mausam: Are They the Same?
No. This is an important distinction.
Mission Mausam is an initiative of the Ministry of Earth Sciences focused on weather and climate science, forecasting, observation, and related services.
There is also Project Mausam associated with the Ministry of Culture, which has different objectives related to cultural connections, maritime routes, and heritage across the Indian Ocean region.
The Ministry of Earth Sciences has specifically clarified that the two initiatives have completely different objectives.
Therefore, when discussing weather forecasting and climate technology, the correct term is Mission Mausam.
What Does “Weather-Ready and Climate-Smart” Mean?
The phrase captures the broader purpose of the mission.
Being weather-ready means having stronger capabilities to observe, forecast, communicate, and respond to weather events.
Being climate-smart means using better scientific information to understand and prepare for climate-related risks over longer periods.
The two ideas are connected.
A community may need a warning about tomorrow’s heavy rainfall while also needing long-term planning for changing rainfall patterns, rising temperatures, or increasing climate risks.
Mission Mausam is intended to strengthen India’s capacity across these different time scales.
What Could Be the Long-Term Impact of Mission Mausam?
The long-term impact will depend on how successfully the mission’s technologies, research, infrastructure, and services are implemented.
If forecasting accuracy and early-warning capabilities improve, the benefits could include better disaster preparedness, improved agricultural planning, more efficient infrastructure management, and stronger climate resilience.
The mission could also strengthen India’s capabilities in atmospheric science and weather technology by encouraging research collaborations and developing skilled professionals.
The government’s stated vision is not merely to improve forecasts but to strengthen India’s resilience to extreme weather and climate change.
