The model is the very-high resolution operational implementation of COSMO model used by the Italian Met Service. The geographic area where the model is being run covers the entire italian pensinsula and major islands. The horizontal resolution is 2.8 km (0.025deg) with 50 vertical levels. The model is routinely run on the ECMWF computing resources once a day at 00Z with hourly output. The boundary conditions (BC) are interpolated from COSMO-ME forecast fields with 1 hour frequency update.

AROME (Application of Research to Operational at Meso-Scale) model is a new NWP system built in order to improve the forecast of mesoscale phenomena and extreme weather events (thunderstorms, mountain forecasts, coastal winds, immediate forecasts). It is planned to be used operationally by the end of 2008 over mainland France. With a 2.5 km horizontal grid mesh and a time step of 60s, this model is designed for short range forecasts. It merges research outcomes and operational progress : the physical package used is extracted from the Meso-NH research model and has been interfaced into the Non-Hydrostactic version of the ALADIN software. AROME also has its own mesoscale data assimilation system based on 3DVar with a 3hours RUC (Rapid Update Cycle). Physical parameterizations used in AROME are: -the ICE3 Meso-NH microphysical scheme with 5 prognostic species of condensed water. It contains 3 precipitating species (rain, snow and graupel) and 2 non precipitating ones (ice crystals and cloud droplets) -the Meso-NH 1D turbulence parameterization with Bougeault Lacarrere mixing lengths. -the externalized version of the Meso-NH detailed surface scheme -the operational ECMWF radiation code (called every 15 min). -the KFB (Kein-Fritsch Bechtold) shallow convection scheme is also switched on. We daily performed 30 hours forecasts with Non-Hydrostatic AROME 2.5 km model, starting from 00 TU. We ran with a time step of 60s over a domain of 400x320 points.AROME is coupled every 3 hours with ALADIN-France (ALADFR) 10km operational model. The post-processing in GRIB files is done on a regular LAT-LON Grid with a 0.025 degree resolution on a DPHASE domain (346x288 points), centered at 46.5N, 9.6E. This domain is smaller than the full DPHASE domain, and on the COPS domain (47-50 N, 6-11 E).

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) Grid description: DDOM: xfirst: 2.0 yfirst: 43.0 xsize: 161.0 ysize: 71.0 xinc: 0.1 yinc: 0.1 xnpole: 0.0 ynpole: 0.0

The Canadian Meterological Centre (CMC) is running the Global Environmental Multiscale (GEM) model in limited-area mode for the duration of the MAP D-PHASE project (1 June - 31 November 2007). The model is run once-daily directly from operational GEM meso-global forecast data (grid spacing of 33 km). A pair of domains are used for the project with horizontal grid spacings of 15 km and 2.5 km. This outer (low resolution or driving) grid is initialized daily at 0000 UTC and covers all of Europe, out to the British Isles, the North Sea, and Nortern Africa. The timestep for this forecast is 300 sec and outputs are available hourly. No regional analysis or data assimilation cycle is undertaken during this project. All observational data will therefore be ingested only indrectly in the regional setup through the outer grid initialization and hourly boundary updates from the meso-global model. The GEM model is a semi-implicit, semi-Lagrangian, two time-level, non-hydrostatic model that runs in a wide variety of configurations. An updated version (v3.3.0) of the GEM model is being used for the MAP D-PHASE project in preparation for the Vancouver 2010 Olympic Games project. This version takes advantage of recent developments designed to enhance the quality of guidance over regions of steeply-sloping orography, including the addition of a 6-category bulk microphysics scheme and time-varying orography over the initialization period.
