Set VI - Atmospheric Model Ensemble extended forecast (ENS extended)

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 purchase of the "Basic Set" +72, +96, +120, +144, +168 hrs is a mandatory prerequisite for the purchase of time steps in the range 12 to 66 hours.

The following sub-sets are available from the ENS extended (46 days) 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)

VI-ii: Extreme Forecast Index (EFI) and Shift of Tails (SOT) 

Product description

EFOV fields at step 360 (change of resolution) can be provided for accumulated fields upon request at no extra cost to customers purchasing the corresponding fields.

Dissemination schedule

(dissemination data stream indicator = F for real-time forecasts)

(dissemination data stream indicator = H for re-forecasts)
