2.2.2. ERA5

The precipitation data obtained from ERA5 forecast product developed through the Copernicus Climate Change Service (C3S). This product has global spatial coverage and covering the period 1950 to the present. Precipitation data are available at an hourly resolution and consist of forecasts initialized twice daily from analyses at 06 and 18 UTC. The ERA5 high-resolution atmospheric data has a resolution of 0.28125 degrees (31 km) but, when downloading the data, there is a possibility to resampling the data to a higher spatial resolution. This will be done for continuous parameters by default through bilinear resampling methods [18]. Therefore, for consistency to other satellite data, we used the precipitation data with 0.1◦ spatial resolution. The data are freely accessible to users from Climate Data Store (CDS) website (https://cds.climate.copernicus.eu).
