Testing/characterization/calibration of bioaerosol on-line monitors/sensors: injection of different bacteria strains and measurement of the detectors response, testing of selection/identification algoritms, comparison with WIBS-NEO response, possibility to include fungi and pollens.  

 

Measurement of bacteria viability vs. atmospheric and air quality conditions: injection of viable bacteria through different nebulizer, production in the chamber of different atmospheric conditions and composition (meteo-climatic, gaseous and aerosol species concentration), monitoring of the bacteria concentration via particle counters and WIBS, collection of viable bacteria through Andersen impactor, liquid impingers, petri dishes, filters. Incubation and counting, microscopic characterization. 
 

LACIS-T provides the possibility of testing (new) instrumentation (e.g., velocity, temperature, humidity, as well as optical particle sensors) and to perform sensor intercomparisons under well-defined laboratory conditions. 
Existing standard operation procedures can be used for comparison of new with established instruments by the user.  
 

The technological services of ACD-C provide comprehensive basic principles for instrument development and strategic improvements.
 

Long-time observation of Physical and chemical properties of aerosols combining online and offline measurements. Ground-based measurements can be completed with vertical measurements (ceilometer, LIDAR, …). 
In addition, the specific flight-restricted area over the station offers the possibility for UAVs, drones, and tethered balloon flights. 
The research site Melpitz can be used for research projects, measurement campaigns, intercomparison, and test facility for new instruments. 
 

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.
