    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 AROME 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 of volcanic ash cloud into the atmosphere. Forecasts cover a global area for a period ranging from 0hour to 94hours starting from the moment of the atmospheric release. The time step is 6 hours, on a regular 0.5degree x 0.5degree grid. 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 the ARPEGE data or the IFS data. The produced fields deal with concentration, time-integrated concentrations and deposits fields. Available data format for outputs are GRIB Edition2, PNG, KMZ and Shape File. Data access is restricted to institutional authorities.
