National Facilities
ACTRIS is the pan-European research infrastructure producing high-quality data and information on short-lived atmospheric constituents and on the processes leading to the variability of these constituents in natural and controlled atmospheres.
ACTRIS promotes the provision of access to a large variety of high-quality services to a wide range of users and needs, for scientific, technological and innovation-oriented usage.
ACTRIS core components are the National facilities, constituting in observatory and exploratory platoforms, and the Central Facilities, fundamental for the provision of harmonized high-quality data.

The CESAR location in Cabauw is characterised by a 213 m high observation tower and surrounding observation field, located 50 km far from the North Sea. The site is ideal for atmospheric research on relations between the atmospheric boundary layer, land surface, weather, climate and atmospheric composition. The site is representative for long-term atmospheric studies because surroundings do not differ significantly from those in 1972 when the site was commissioned.
Training of users (scientists, private sector) in instrument handling, campaign planning, calibration procedures, or application of algorithms. On-site training as well as virtual training is possible.
The QUAREC facility (the simulation chamber and the analytical instruments) allows investigating:
- homogeneous gas-phase reaction systems (determination of rate coefficients and products formation for the reactions of OH, NO3 halogens and ozone with VOCs)
- formation of airborne particulates in homogeneous gas-phase reaction systems.
Estimated duration: None, but the request of access should be sent at least 2 months in advance.
The Cabauw site offers expertise, service and training for UV-VIS trace gas remote sensing intercomparisons as part of the ACTRIS topical center for trace gas remote sensing (CREGARS).
