Summary
These data sets contain data at the resolution of the ensemble prediction
forecast system in operational use at ECMWF. Since the resolution and internal
representation of the archive may vary according to changes in ECMWF's
operational practice, data services associated with these data sets include the
provision of interpolation to requested resolutions and ... representation forms.

Five data sets are separately supported:

- Control Forecast
+ Surface ensemble
+ Pressure level ensemble
+ Model level ensemble
+ Wave model ensemble


- Perturbed Forecast
+ Surface ensemble perturbed forecasts
+ Pressure level ensemble perturbed forecasts
+ Wave model ensemble
