  • Dust forecast is done using Dust Regional Atmospheric Model with 8 categories for dust particle sizes which is assimilating ECMWF dust analysis in dust initial field (DREAM8assim). Model is embedded in NCEP Nonhydrostatic Mesoscale Model on E-grid (NCEP/NMME). Initial and boundary conditions are from ECMWF global forecast. Model resolution is 1/5 degrees. Model runs are delayed one day because of availability of dust analysis fields and output is available daily at 17UTC.

  • Multi-Model Ensemble forecasts of air quality and of the atmospheric composition on Europe. The Ensemble forecast is the median of the CHIMERE, EMEP, EURAD, LOTOS/EUROS, MATCH, MOCAGE and SILAM models forecasts. Parameter : concentration of O3 (ozone) at surface level. Unit : μg/m3. Forecasts from step +25H to step +48H, i.e from validity time D+1 01 UTC to validity time D+2 00 UTC (D 00 UTC reference time), with a time step of 1 hour. D is the reference time day. Spatial resolution on a regular latitude x longitude grid of 0.1x0.1 degree. NetCDF format. A report stating conditions of ensemble prediction production is also available on download. More information can be found in the technical guide available on the CAMS regional website in the documentation category.
