    This short course is part of the 2020 EGU General Assembly (SC1.21), it is an opportunity to learn about Copernicus data for Atmospheric Composition and get examples of how to develop your own workflows based on sample applications. 

    Webinar - 26 May at 10:30 CEST  (slide deck of the webinar available here in the presentations folder)

    • 10' Introduction and quick Slido polling session on topics for the hands-on session.
    • 20' The data (ESA, CAMS, EUMETSAT).
    • 30' Hands-on examples based on participants feedback gathered with Slido (Julia Wagemann, MEEO).

       

    The sessions will be hands-on and supported by Earth Observation and Model experts to discover data, handle them and produce plots out of a sample of the Copernicus data. You will make use of a series of freely available tools specifically developed for these applications, including Jupyter Notebook modules, to have an easy and intuitive way to make use of Python programming.
    No experience is necessary as various exercises will be provided for a wide range of skill levels and applications.
    It is recommended to join via laptop.

    Note: Slido will accompany the webinar session to collect your comments and answer your questions. The slido event will also stay open for the entire week (26-29 May) to support you during your individual data discovery.

    (3) Discover the data yourself and pick your dataset to play with

    A self-paced activity to start after the webinar until May 29th. You will receive support on slido with your questions.

    (4) 29 May, at 10:30 CEST. Sharing results, feedback and course evaluation (zoom link provided via email to registered participants)

    A final interactive sessions to discuss results, difficulties and provide us with your feedback.


    Few additional info:

    The European Union Copernicus programme is open and free for everyone - whether from academic, government, or commercial backgrounds. The programme has an operational focus, with satellite constellations and services. 

    Satellite data provides vital information on key atmospheric constituents, at different spatial and temporal scales, with continuous improvements in observational spatial and temporal resolution, coverage and measured species as well as a constantly evolving added value products from the Copernicus Atmospheric Monitoring Services.

    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-A, -B, and -C satellites. These products include column-integrated concentrations of different trace gases such as nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2), carbon monoxide (CO) UV-radiation, aerosol index as well as ozone profiles.  Important applications of AC SAF data include monitoring global air quality and UV-radiation reaching the Earth's surface. This section describes the observations from GOME-2 instrument relevant for this training and how to access the data. IASI  observations are described in a separate section.

      Mark as done

      AC SAF provides three different types of datasets of GOME-2 observations: Near Real Time, Offline,  and Data Records. One of the main differences between these datasets is the time they are provided for users: NRT is available within 3 hours from observation, whereas Offline data becomes available typically within 1-3 days delay. 

      The primary dataset that will be used in this course is Level 2  Offline data of Absorbing Aerosol Index  (AAI). 

      Sources for browsing GOME-2 AAI images without downloading the data 

      1. The Temis service provided by KNMI provides near real time (last 24 hour composite) and an archive of global AAI images from GOME-2 instruments (A,B,C). Registration is not needed.

      2. The SACS service provide also NRT and archived images of GOME-2 AAI. In this service you can also compare the AAI to other instrument observations, such as TROPOMI. There is also zoom in option, where you can select a specific grid on the globe. Registration is not needed.
