Indian government plans to use GIS to improve weather forecast system

SHARE

Indian Meteorological Department (IMD) has a proposal for Rs 500-crore investment plan over the next two years. Subject to the Planning Commission approval, the project would cover installing dense network of satellite-based rain gauge stations for online monitoring and automatic weather surface stations for adequate coverage of weather data. It would also include setting up wind profilers, a dense network of radars for complete coverage of coastal areas for cyclone monitoring.

The Government plans to develop an integrated analysis forecast system with improved data assimilation with the use of high-density data. This is aimed at fine tuning the model forecast and downscaling it to district level, using statistical tools and GIS. Soon, the Government will start making available its latest weather updates and forecasts up to seven days at the district level and at its Web site. It also plans to give farm advisories based on weather forecast at district level. IMD has introduced an integrated meteorological data reception and analysis system (IMDRAS) that enables reception of processed information even in remote areas through a personal computer.
