The Czech Republic has become a founding partner country of the European research infrastructure ACTRIS ERIC, which was established by the decision of the European Commission as of April 25, 2023. The Czech Republic is represented by the Global Change Research Institute of the Czech Academy of Sciences, the Czech Hydrometeorological Institute, the RECETOX center of Masaryk University, the Institute of Chemical Processes Fundamentals of the Czech Academy of Sciences and the Institute of Atmospheric Physics of the Czech Academy of Sciences.
To put it in perspective, what CERN is to nuclear physics, ACTRIS is becoming to atmospheric sciences. And it’s not an exaggeration. The ACTRIS infrastructure is a key experimental base for the study of atmospheric aerosols and their interactions with clouds and reactive gases in the atmosphere. Aerosols, clouds and reactive gas components are studied both at ground stations and using remote sensing methods. It is a distributed infrastructure with 224 national nodes (including both stationary and mobile measurement platforms as well as experimental chambers) in 22 European countries (represented by more than 100 research organizations), 6 pan-European calibration centers spread over 11 countries, data centers and a management office in Helsinki.
