  • is run twice daily, base times 00 UTC and 12 UTC, producing a 10 day forecast (Day0 to Day10) and also a 15 day forecast (Day0 to Day15). 
  • has horizontal resolution of 9 Km and vertical resolution of 137 model levels.  These values are the same as those of the High Resolution (HRES) in IFS versions before Cy48r1).
  • has land-atmosphere and ocean-atmosphere coupling.
  • has 50 ensemble members plus an unperturbed control member (CONTROL-10 for the 10 day forecast, CONTROL-15 for the 15 day forecastCTRL).
  • CONTROL-10 is the unperturbed ensemble member and The unperturbed control member (CTRL) corresponds to the High Resolution (HRES) in IFS versions before Cy48r1.

The ensemble consists of one unperturbed control member (CONTROL-10 or CONTROL-15CTRL) and 50 perturbed members that are similar to the control member but their initial states and model physics have been perturbed to explore the currently understood range of uncertainty in the observations and the model.  A set of medium range re-forecasts provide a basis for the medium range model climate medium range model climate (M-Climate).
