Effective immediately, all forecasts will be evaluated against initial ECMWF Reanalysis version 5 (ERA5) release data (ERA5T)
This change is necessary due to restricted access to MSWEP data for commercial entities.
Post-processed precipitation training data and precipitation-based evaluation datasets, including recent rainfall totals and historical quintile boundaries, are now exclusively derived from ERA5 or ERA5T. These updated datasets are available via the AI Weather Quest Python Package.
