International technology company IBM plans to make a high-resolution weather forecast model that will also rely on user-generated data to improve the accuracy of forecasts available in India.IBM GRAF, as the forecast system is called, can 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.
