Services

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 service consists of:
- Provision of data from simulation chamber experiments,
- possibility to perform 6hr experiments in the simulation chamber, 
- technical service to use own instruments,
- training for planning, evaluation and interpretation of experiments. 
- Hands-on training sessions with state of the art instrumentation connected to PACS-C2 
- Training on how to perform chamber experiments by experienced scientists.

Aerosol generation and ageing in the temperature range -16 to 26°C and possibility for ramping of temperature during experiments. 
Sea spray simulation chamber (AEGOR) can be connected to the AURA chamber.
A suite of state of the art on-line and off-line methods are available for gas and particle characterization.

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).

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. 

The Cabauw site offers expertise, service and training for cloud radar calibration as part of the ACTRIS topical center for cloud remote sensing (CCRES).
