Ensemble Prediction System (EPS) Data Sets

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 representations.

 Five data sets are supported separately:

• 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
