Remote

Training through research of:
a) operation and calibration techniques of remote sensing and in situ instrumentation available in AGORA 
b) algorithms for retrieval physical magnitudes from remote sensing instrumentation (LIRIC, GARRLIC, POLIPHON). This training can be performed by remote access

The service includes:

Custom experiments on aerosol chemistry and physics: ChAMBRe is a multi-purpouse facility connected to a laboratory fully equipped for aerosol sampling and characterization. 
Specific experiments/tests can be organized with the support of the ChAMBRe teams. 
 

Testing and calibration of aerosol samplers and aerosols/gas monitors (e.g. low-cost detectors): connection/introduction of the samplers/detectors to/in the chamber, production of different aerosol and gas species, comparison of the detectors response with those of the ChAMBRe reference equipment. 
 

Multi-wavelength on-line and off-line measurement of the optical properties (absorption and scattering) of atmospheric aerosols: injection of different aerosol species (soot, dust, salt, organic), modulation of the meteo-climatic conditions, on-line measurement by 3-lambda photoacoustics monitors (PAXs), OPS and SMPS, sampling on filters/impactors and off-line analyses by Multi Wavelength Absorbance Analyzer (MWAA)and two-lambda thermo-optical analysis. 
 

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. 
 

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. 
Cabauw is one of very few observatories around the world that monitors such a wide scope of relevant processes in atmospheric chemistry and physics, hydrology, meteorology, climate, and atmospheric chemistry.
The observational programme includes the following topics:
-        Operational meteorological station
-        Operational air quality monitoring station
-        In-situ observations of meteorological parameters, including extensive land-atmosphere interaction.
-        Energy balance observations including flux measurements.
-        Radiation observations, including a Baseline Surface Radiation Network (BSRN) installation and hemispherical cloud cover observations.
-        A suite of aerosol remote sensing instruments, including a high-performance multi-wavelength Raman lidar for aerosols, clouds and water vapour, a ceilometer and a UV-depolarisation lidar.
-        A suite of (scanning) cloud remote sensing instruments, including 3/35/94 GHz cloud radars, microwave radiometers
-        Precipitation observations including a scanning drizzle radar, micro rain radar and disdrometers.
-        Wind profile observations along the tower up to 200 m and a scanning Doppler wind lidar
-        Greenhouse gas observations at four different levels in the tower between 20 m and 180 m.
-        In-situ aerosol observations, including scattering and absorbing aerosol properties, as well as chemical speciation and isotope analysis.
-        Atmospheric composition measurements using in-situ observations and UV-VIS remote sensing.
In addition, the specific flight-restricted area over the station offers the possibility for drones, and tethered balloon flights.
The Cabauw site offers access for research projects, measurement campaigns, intercomparisons, and test facility for new instruments, as well as training.
