    Welcome to the Second Joint Training Course on Atmospheric Composition   

    16 - 20 November 2020

    The European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), European Center for Medium-Range Weather Forecast (ECMWF) with the Copernicus Atmosphere Monitoring Service (CAMS) are organising a second joint training course on Atmospheric Composition with a focus on air quality and data interoperability.

    The school will be fully on-line with lectures, discussions and practical sessions. We aim at fully involving participants in an interactive way.

    The specific goals of the course are:

    1. Present the state-of-the-art in air quality monitoring and modelling,
    2. Provide an overview of the different observations, tools and applications,
    3. Enhance the capacity on data access and analysis of existing and new satellite data products and monitoring services,
    4. Foster participants driven personal and team projects.

    We have prepared for you a number of resources that we invite you to look at before the course starts. Here's what you can do on this page:  

CAMS aerosol and atmospheric composition

  • CAMS aerosol and atmospheric composition

    The Copernicus Atmosphere Monitoring Service (CAMS, provides consistent and quality-controlled information related to air pollution and health, solar energy, greenhouse gases and climate forcing, everywhere in the world. It is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf the European Commissions and is one of six Copernicus data services. The principal CAMS datsets are global forecasts and analyses of reactive gases (O3, CO, NO2, SO2, HCHO), greenhouse gases (CO2, CH4) and aerosol optical depth. In addition to the atmospheric composition products, CAMS also provides data on global fire emissions and inventories of anthropogenic and biogenic emissions. Examples of CAMS charts, for an aerosol forecast and fire activity analysis, are shown below and the latest charts can be viewed at

    CAMS analyses assimilate a wide range of satellite observations of meteorology and atmospheric composition (including from the Atmospheric Composition SAF and TROPOMI/Sentinel-5p), and initial conditions for the forecasts are taken from the analyses. A full list of the satellite observations can be found at In situ observations made at the ground and from aircraft and balloons are also vital to CAMS and are used to regularly evaluate and validate the datasets. Validation reports for the CAMS data can be found at
