The products consist of control and perturbed forecasts plus the equivalent deterministic products. The fields are provided in GRIB2 encoding.
Reforecast fields are optional.
Interval/period: N/A
A daily clustering of the forecast fields from the ENS similar in principle to the old ENS clustering but using a different algorithm. The daily clustering determines weather scenarios, defined as the ensemble members closest to the centroid of each cluster.
Note that only a fixed domain of Europe is available for this product.

The products provide the probabilities of the occurrence of instantaneous and averaged or accumulated weather events at each grid point. The products are encoded in GRIB form.

The ENS provides the ensemble mean (or the ensemble median) forecast which tends to average out the less predictable atmospheric scales.

The spread of the ENS forecast, measured by the standard deviation (Std) of ENS values at a given point and lead time, is normalised against the mean of the spread of the 30 most recent 00UTC ENS (Mstd) for 00UTC runs (or 12UTC ENS (Mstd) for 30 most recent 12UTC ENS runs) for the same lead-times and geographical locations.
