The high resolution satellite precipitation product is based on the integration of multiple precipitation and rainfall datasets to generate a high spatial (1 km) and temporal (daily) resolution precipitation product over the Mediterranean area. GPM-Late run and CPC precipitation datasets are here downscaled and merged together. These products are originally at coarse spatial resolution (>10 km) and have been downscaled to 1 km spatial resolution using CHELSA (1 km) climatology. The two products are then merged with a triple collocation technique (third product: ERA5 Land precipitation, downscaled with the same technique). The product has been developed in the framework of the 4D-MED Hydrology project. The product is available in the period 2015-2022.
