India Advances Weather Forecasting With DBNet Stations
The National Centre for Medium Range Weather Forecasting (NCMRWF) and New Space India Limited (NSIL) have joined forces to enhance India’s weather prediction capabilities. This collaboration under the Mission Mausam project involves setting up two Direct Broadcast Network (DBNet) stations in Delhi/NCR and Chennai. These stations will enable near real-time satellite data reception and processing from Low Earth Orbit (LEO) satellites. This initiative marks step in improving weather forecasts, cyclone monitoring, and climate research in India and globally.
DBNet and Its Role in Weather Forecasting
DBNet is a global system designed to receive satellite data directly as satellites pass overhead. This immediate data capture reduces delays common in traditional satellite data methods. By processing data within minutes, DBNet supports Numerical Weather Prediction (NWP) models that require timely and accurate inputs. The system enhances short- to medium-range forecasts and helps in disaster risk reduction.
Infrastructure and Coverage
Two DBNet stations will be established in Delhi/NCR and Chennai. These locations cover a broad geographical area important for India’s weather monitoring. The stations will receive data from Indian and international Earth Observing System (EOS) satellites such as Oceansat, NOAA, and MetOp. The design allows future integration of next-generation satellites, ensuring scalability and long-term relevance.
Benefits of Real-Time Data Acquisition
The direct broadcast method eliminates the latency caused by routing data through central ground stations. This leads to faster availability of satellite information. NCMRWF aims to complete data processing within five minutes of satellite overpass. This rapid processing enables more accurate and timely weather forecasts, which are crucial during extreme weather events like cyclones and floods.
Global Collaboration and Data Sharing
India’s DBNet initiative aligns with the World Meteorological Organization’s (WMO) satellite data policies. Processed data will be shared internationally via the WMO Information System – 2.0 (WIS 2.0). This strengthens India’s role in global weather prediction efforts and supports international users with timely Earth observation data. The initiative contributes to improving global DBNet coverage and enhances climate monitoring worldwide.
Impact on Disaster Management and Climate Research
Improved data availability and forecast accuracy aid disaster preparedness and response. Early warning systems benefit from timely satellite information. Climate researchers gain access to high-resolution data supporting long-term studies. The DBNet stations will thus play a vital role in reducing disaster risks and advancing scientific understanding of weather and climate.
