The Copernicus Atmosphere Monitoring Service General Assembly

This week, Ineris is attending the seventh Copernicus Atmospheric Monitoring Service (CAMS) General Assembly in Valencia, Spain. The Institute will be presenting its work in the fields of air quality forecasting and air quality public policy support services.

The Copernicus Atmospheric Monitoring Service (CAMS) provides the public, decision-makers and the business world with a wealth of information on the chemical composition of the air. This includes information on air quality, the behaviour of the ozone layer, UV radiation and the impact of greenhouse gases on the climate.

All this data is openly available and can be used by both public and private users.
Almost 200 experts will gather this year in Valencia. The key topics of interest for Ineris concern:

  • the use of AI algorithms to improve air quality forecasts;
  • analysis of the impact of methane emission reduction scenarios on reducing ozone peaks;
  • the incorporation of Sentinel 5P satellite data into European air quality models: the Institute and Météo-France in the CAMEO (Copernicus Atmosphere Monitoring Evolution) project;
  • the National Collaboration Programme, which seeks to improve the use of CAMS products and services in national air quality forecasting platforms, particularly Prev’air in France;
  • the impact of forest fire emissions on air quality, as estimated using satellite observations;
  • assessment of the impact of natural sources of fine particles, such as desert dust, on fine particle peaks (in collaboration with FAIRMODE);


The European Commission has entrusted the European Centre for Medium-Range Weather Forecasts (ECMWF) with implementing and managing the Copernicus Atmospheric Monitoring (CAMS) and Copernicus Climate Change (C3S) Services.   The Annual General Assembly is an opportunity for organisations contributing to the development of these services, as well as users and European authorities, to review the latest developments and their performance.
In collaboration with Météo-France, Ineris coordinates the Operational Production Department (Service de Production Opérationnelle) for the supply of daily forecasts and maps of air quality in Europe, as well as reanalyses following its development over recent years. Ineris is particularly involved in helping to produce this information by applying the CHIMERE model to establish air quality forecasts for Europe, in much the same way as it does for the French national platform Prev’Air. Ten other European modelling teams are active in this department.
The Institute is also responsible for the dedicated Decision Support Service (Policy Department), which develops products and tools suited to the expectations of European national authorities. These are designed to provide relevant information for the analysis of air pollution events and their determining factors, particularly for the implementation of European directives on air quality.
CAMS services rely on combined real-time use of local and satellite-based observations and modelling outcomes. As part of its role at the Aerosol Chemical Monitor Calibration Centre (ACMCC) within the ACTRIS European research infrastructure, Ineris is active in processing empirical data on the chemical composition of particulates and developing real-time data transfer and validation procedures.
