Twice a week, the ENS model is extended up to 46 days. ENS extended products comprise ensembles of individual forecasts and post-processed products of average conditions (e.g. weekly averages) and the associated uncertainty.

The following sub-sets are available from the ENS extended (Monthly) on both Monday and Thursday runs:

VI-i: Weekly means of ensemble means (including re-forecast products)

VI-ii: Weekly mean anomalies of ensemble means

VI-iii: Weekly means of individual ensemble members (including re-forecast products)

VI-iv: Weekly mean anomalies of individual ensemble members

VI-v: Individual forecast runs (including re-forecast products)

VI-vi: Probabilities (weekly products)
