CAMS Global atmospheric composition forecast production system is used to produce the daily forecasts of pollutants, aerosols and greenhouse gases across the globe. Satellite observations of atmospheric composition are merged with a detailed computer simulation of the atmosphere using a method called data assimilation. The resulting analyses, i.e. maps of atmospheric composition, are used as initial conditions for the daily forecasts of atmospheric composition. Analyses and forecasts for aerosols and chemical species are produced twice a day.
CAMS Global analysis and forecast daily data at approximately 40km spatial grid (T511 spectral) on 137 levels. For more details please see: CAMS: Global atmospheric composition forecast data documentation.
