This product is based on data and products of the European Centre for Medium-range Weather Forecasts (ECMWF) but has been modified by Salient Predictions.
Regridded from the native O320 Gaussian grid to a regular 0.25deg rectangular grid
Temporally aggregated to match Salient's weekly and monthly S2S forecast products
Debiased relative to ERA5 by computing a model climatology from the reforecast set, subtracting it from the raw values, and adding back Salient's ERA5 climatology </aside>
