title2018-05-15 COSMO-DE-EPS replaced by COSMO-D2-EPS

The new set-up of COSMO model ("COSMO-D2") replaces the former COSMO-DE.  Methods of EPS member generation has not changed. The major changes:

  • grid spacing reduced from 2.8 km to 2.2 km
  • number of vertical levels increased from 50 to 65 with higher resolution in the boundary layer
  • model domain enlarged, mainly to the west

The updated description is available here.

title2017-03-21 COSMO-DE-EPS model update

Following major changes apply to COSMO-DE-EPS update:

  • the use of four global models via BCEPS for initial and boundary conditions is switched off
  • initial conditions are provided by analysis members of an Local Ensemble Transform Kalman Filter
  • boundary conditions are provided by members of ICON-EPS (40 km grid size with a two-way nested grid of 20 km over Europe)
  • additional parameters of physics packages are perturbed
  • selection out of a set of predefined parameter perturbations is randomized (selection performed for each forecast start)
  • stochastic perturbations of SST and soil-moisture on specific spatial scales

The model description is available here.
