ACTRIS Czech Republic

LRI ACTRIS-CZ is continually monitoring and measuring air quality in the means of regional level and in Europe using the ground-based research facility of the National Atmospheric Observatory Košetice (NAOK), Observatory Milešovka, station Suchdol and Lom.

For users, we offer open access to data and infrastructure (possibility of own measurement, use of measurement space, co-measurement, excursions and educational seminars).

What are the main activities?

The ACTRIS Czech Republic (ACTRIS-CZ) large research infrastructure (LRI) forms a unique platform for the long-term background air quality monitoring and research closely related to climate, environmental and health issues qualified as society challenges. 

ACTRIS addresses the scope of integrating state-of-the-art European ground-based stations for long-term observations of aerosols, clouds and short lived gases. ACTRIS represents a fundamental step towards the establishment of the atmospheric component of the Integrated European Observing System and a clear upgrade in services offered to users.
