    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:

    The main objectives of EUMETSAT Atmospheric Composition SAF (AC SAF,  is to process, archive, validate and disseminate atmospheric composition products from GOME-2 and IASI instruments onboard EUMETSAT Metop satellites. These products include e.g. total columns of different trace gases such as nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2), tropospheric column of NO2, CO, UV-radiation, aerosol index as well as ozone profiles.  This section describes the products relevant for this course obtained from GOME-2 instrument, while IASI products are described in separate section.  Important applications of AC SAF data are e.g. monitoring global air quality or UV-radiation reaching the Earth's surface. In this section you will learn about AC SAF data products, what kind of studies they are useful for, and how you can access the data. 

    AC SAF provides three different types of datasets of GOME-2 observations: Near Real Time, Offline,  and Data Records. The datasets that will be used in this course are:

    • Level 2 Near Real Time (NRT) data (trace gases)
    • Level 2  and Level 3 Offline data (trace gases, absorbing aerosol index)
    • Level 3 Data Records (trace gases)
