By observing and analysing precipitation, soil moisture and snow, it helps in flood forecasting, drought prediction and water supply planning. Collaborating with hydrological agencies and organisations, the H SAF targets the optimised use of satellite data in hydrological models. Its contributions are vital in enhancing our ability to manage water-related challenges effectively.
