The CNMCA-LETKF data assimilation system is operationally used to initialize the high-
resolution non-hydrostatic model COSMO integrated over the Mediterranean-European
region. The atmospheric short-range ensemble prediction system based on the LETKF
system and the COSMO model is under testing at CNMCA since july 2013
MAIN CHARACTERISTICS:
Domain and resolution:
Mediterranean-European domain
0.09° grid spacing (~10 km) and 45 vertical levels
40+1 ensemble members
IC and BC: initial conditions are derived every 6 hours from the CNMCA-LETKF system.
Lateral boundaries conditions are from IFS deterministic run perturbed using ECMWF-EPS.
Surface perturbations: climatological perturbed sea surface temperature.
Model error: stochastics physics perturbation tendencies.
Forecast range: the 40+1 COSMO forecast members will run up to 48 hours at 00 UTC.

NETTUNO (Sea State) EPSpart of MYWAVE project
NETTUNO is a high resolution local scale wave forecast system operational in the
Mediterranean Sea based on the COSMO-ME and WAM models (In cooperation
with ISMAR-CNR of Venice)
The sea state probabilistic forecast is obtained driving the wave model using the
hourly COSMO-ME EPS wind forecast members
The NETTUNO-EPS consists of 40+1 members, that are integrated at 00 UTC up
to 48 hour forecast in the Mediterranean basin
Validation of sea-
state forecast has
been done at
ISMAR-CNR
