ACTRIS - Largest multi-site infrastructure for atmospheric research worldwide officially launched

Brussels/Leipzig, 26.04.2023

ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure) was established as a European research infrastructure to provide science, industry and public authorities with access to a wide range of high-quality data, technologies, services and resources, and to promote cutting-edge research and international cooperation in the field of atmospheric research.


The European Commission has officially established ACTRIS as a European Research Infrastructure Consortium (ERIC). With its ERIC status, ACTRIS is now officially recognised as a European research infrastructure for atmospheric research. The establishment of ACTRIS in Europe will run until 2025, after which ACTRIS will move into the operational phase. By then at the latest, all ACTRIS services will be accessible via

The statutory seat of the ERIC is Finland and the Head Office is located in Helsinki. Other central institutions as well as the national institutions providing ACTRIS services are spread across the 17 ACTRIS member countries.

A total of 11 universities, research institutes and authorities are involved in the German ACTRIS contribution (ACTRIS-D). The establishment of the German calibration centres, observation stations, atmospheric simulation chambers and mobile measurement platforms is being funded by the Federal Ministry of Education and Research (BMBF) with a total of 86 million euros over eight years. At the same time, the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) has taken over the financing of the German member contribution and the operation of the German calibration centres. ACTRIS-D is coordinated by the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig.
