M Ravichandran, Secretary of the Ministry of Earth Sciences, inaugurated the Open-Field Observatory of the Coastal Atmospheric Research Testbed (C-ART) at Andhra University in Visakhapatnam on May 8, 2026. This ₹180 crore facility, established by the Indian Institute of Tropical Meteorology (IITM), Pune, marks India’s first specialized weather testbed on the east coast. The observatory is a key component of Mission Mausam, aimed at enhancing the nation’s capacity to predict and manage extreme weather events.
Enhancing Coastal Weather Prediction through C-ART
The Coastal Atmospheric Research Testbed (C-ART) is designed as a specialized national user facility to bridge critical gaps in the understanding of complex atmospheric processes along India’s coastline. By providing high-resolution, continuous data, the observatory helps scientists diagnose monsoon convection, tropical cyclones, and intense thunderstorms with unprecedented precision. This real-time data stream is essential for refining Numerical Weather Prediction (NWP) models, which serve as the backbone of modern weather forecasting.
The facility allows researchers to conduct process-level studies on land-ocean-atmosphere interactions. These studies are crucial for the development of early warning systems that can save lives and protect infrastructure during extreme weather events. By capturing the microphysical properties of clouds and the dynamics of the Atmospheric Boundary Layer (ABL), C-ART provides the granular information needed to transition from general forecasts to site-specific, actionable weather intelligence.
Why Visakhapatnam Was Chosen for the Testbed
Visakhapatnam, often known as the Jewel of the East Coast, offers a unique vantage point for atmospheric research due to its proximity to the Bay of Bengal. This region is highly prone to intense cyclones and heavy rainfall, making it an ideal site for monitoring the life cycle of tropical storms in real-time. The area’s coastal geometry creates distinct sea breeze and land breeze patterns that significantly influence the local climate and weather extremes.
By establishing the testbed at Andhra University, which was founded in 1926, the project leverages the academic expertise of one of India’s oldest and most prestigious institutions. The facility fills a critical geographical gap in the country’s meteorological network. While the western coastline is monitored by research facilities in locations such as Mahabaleshwar and Mumbai, the eastern coast required a dedicated hub to study the unique dynamics of the North East Monsoon and the impact of the Madden-Julian Oscillation (MJO) on the Indian subcontinent.
Mission Mausam: India’s Path to Weather Readiness
The C-ART facility is a major milestone under Mission Mausam, a national initiative approved by the Union Cabinet on September 11, 2024. With an initial outlay of ₹2,000 crore for the first phase ending in 2026, the mission aims to transform India into a weather-ready and climate-smart nation. A key objective is to enhance the accuracy of weather forecasts to the Panchayat level by 2030, which will significantly benefit agriculture, aviation, disaster management, and the defence sector.
The mission is driven by three primary institutions under the administrative control of the Ministry of Earth Sciences (MoES). These include the India Meteorological Department (IMD) for observational services, the Indian Institute of Tropical Meteorology (IITM) for specialized research testbeds, and the National Centre for Medium-Range Weather Forecasting (NCMRWF) for data assimilation. By integrating Artificial Intelligence (AI) and Machine Learning (ML) with traditional physics-based models, Mission Mausam seeks to provide highly reliable, real-time weather information across the country.
Advanced Technical Infrastructure of C-ART
The Open-Field Observatory at Andhra University is equipped with state-of-the-art instrumentation designed to capture complex atmospheric data with high precision. Key features of the facility include Doppler Weather Radars for tracking precipitation, Scanning Wind Lidars for monitoring wind profiles in the lower atmosphere, and advanced Wind Profilers. These instruments allow scientists to study aerosols, clouds, and rainfall dynamics in real-time.
| Instrument | Primary Function |
|---|---|
| Disdrometer | Measures the size distribution and velocity of raindrops |
| Eddy Covariance Tower | Tracks the flux of heat and moisture between land and atmosphere |
| Wind Lidar | Provides high-resolution profiles of wind speed and direction |
| Aerosol Observatory | Monitors suspended particles that influence cloud formation |
This technical infrastructure is overseen by the Indian Institute of Tropical Meteorology (IITM), Pune. Founded in 1962 and functioning as an autonomous body since 1971, IITM is the nation’s leading center for basic and applied research in monsoon meteorology. The Ministry of Earth Sciences (MoES), established in 2006, provides the strategic funding and administrative support for C-ART, ensuring that India remains at the forefront of global meteorological research.
