HydroPy was driven by daily ERA5 forcing data from 1940-2024 to generate daily fields of surface and subsurface runoff at the ERA5 resolution. Note that the data arrays start at the North Pole, i.e. the
To generate river runoff, the HD model was operated globally at 5 arc minutes (1/12°) horizontal resolution. First, the forcing data of surface and sub-surface runoff simulated by HydroPy were interpolated
