About us

The ACTRIS-CZ Research Infrastructure (RI) focuses on topics of regional air quality in the Czech Republic and in broader perspective also in Central Europe. It consists of the Košetice National Atmospheric Observatory together with the equipment and facilities of other research institutions carrying out there their research and monitoring activities.

The recipient of the support and the coordinator of the project is the Czech Hydrometeorological Institute.

ACTRIS-CZ RI is composed of the following subjects:

The Czech Hydrometeorological Institute (CHMI)

The Institute of Chemical Process Fundamentals of the Czech Academy of Sciences, p. r. i. (ICPF)

The Global Change Research Institute of the Czech Academy of Sciences, p. r. i. (GCRI)

The Research Centre for Toxic Compounds in the Environment of Masaryk University (RECETOX)


ACTRIS-CZ RI provides expert outputs in the field of atmospheric sciences, related particularly to monitoring and research of atmospheric aerosols, reactive gases and meteorological parameters.

The set of RI measurements includes the following activities:

  • Long-term monitoring of air quality within the CHMI monitoring network,
  • Measurement of volatile organic compounds, nitrogen oxides and elemental and organic carbon,
  • Monitoring of newly introduced organic substances which are analysed in ambient air, atmospheric deposition, surface water, sediment, soil, moss and lichen,
  • Automated measurements of the physical and chemical properties of aerosol particles in the air (e.g. particle size distribution and their number concentration, monitoring the ability of particles to bind atmospheric water and their thermal stability, optical properties of aerosols),
  • Continuous measurement of greenhouse gasses concentrations and selected pollutants,
  • Measurement of meteorological parameters both at ground and in the vertical profile.
