    Forecasts of pollutant plume dispersion in the atmosphere for a period ranging from 0hour to 24hours starting from the moment of the pollutant release . The time step is either 30 minutes or 1hour depending on the output data format.The resolution of the dispersion model is 1 km on a regular grid of 60 km X 60 km, and 4 km on a regular grid of 240 km x 240 km centered on the source of the emission. The PERLE system is based on a lagrangian particular dispersion model forced by the MesoNH meteorological model coupled with ARPEGE meteorological model. The outputs are : concentration, time-integrated concentrations and deposit fields. The available data formats are GRIB edition 2, PNG, KMZ and Shape file. Data access is restricted to institutional authorities.

    Forecasts using backward-time modelling of the dispersion of radionuclide plumes in the atmosphere. Forecasts cover a global area for a period ranging from 0hour to 360hours starting from the moment of the atmospheric release. The time step is 3 hours, on a regular grid of 1degree X 1degree, in text format. Unit: Bq/m3. The forecasts are based on the MOCAGE-ACCIDENT model which is a specific version of the atmospheric dispersion model MOCAGE (Model of Atmospheric Chemistry of Large Scale) developed at Météo-France by CNRM. Meteorological forcing is provided by ARPEGE data. The produced fields deal with radionuclide concentrations. Data access is restricted to institutional authorities.
