    On this Moodle page we are hosting a number of resources to help in handling datasets and prepare for the training course.

    In order to be ready:

    • Find out how you can register for a number of services.
    • Download a number of datasets as instructed in the sections below and get ready to read and handle datasets.
    • Watch the Atmospheric Composition MOOC videos that provide a general background on Atmospheric composition

CAMS aerosol and atmospheric composition

  • CAMS aerosol and atmospheric composition

    The Copernicus Atmosphere Monitoring Service (CAMS, https://atmosphere.copernicus.eu/) 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 https://atmosphere.copernicus.eu/charts/cams/.

    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 https://atmosphere.copernicus.eu/satellite-observations. 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 https://atmosphere.copernicus.eu/node/325.
