dphase_aladfr: ALADIN-France operational model forecasts run by Meteo-France for the MAP D-PHASE project

DOI

ALADIN is the operational model at Meteo-France. The horizontal resolution is 9.5km, the time step : 415s with a Semi-lagrangian scheme. There are 46 vertical levels with 15 levels below 3000m. The domain of the integration is : (-11.84W, 33.14E) (25N,56.95N)

Physical parameterization:
- the micro-physics scheme use 4 prognostic variables: liquid and ice cloud water, rain and snow.
- the convection scheme is based on Bougeault (1985) with a donwdraft parameterization.
- the operational ECMWF radiation code which is called every 60 minutes.
- the burbulence is based on Louis's function with an interactive mixing length.
ALADIN is coupled with ARPEGE every 3 hours and has its own assimilation system based on 3DVAR.
The post-processing in GRIB files is done on a regular LAT-LON Grid with a 0.1 deg resolution on the DPHASE domain.

ALADIN-FRANCE daily performs 54h forecasts starting at 0TU, 6TU, 12TU, 18TU (only the 0UTC forecast until 30h is sent)
