Why in news
International technology company IBM plans to make a high-resolution weather forecast model, named IBM GRAF (Global High-Resolution Atmospheric Forecasting System), that will rely on user-generated data to improve the accuracy of forecasts available in India.
- It will generate forecasts at a resolution of 3 kilometres. This is a significantly higher resolution than the 12-kilometre models used by the India Meteorological Department to generate forecasts.
- Weather forecasts will be available to individuals for free download and can be used by farmers. The forecast system will also be used to provide custom forecasts for energy companies, consumer brands, insurance businesses and satellite imagery analysts.
- For its forecasts, IBM will rely on a global network of sensors — automatic weather station, data buoys and barometric pressure data from cell phones of users who will download the application.
- It will run on supercomputer and generate forecasts over desired time-frames — three days, weekly or fortnightly.
