Planning, installation, commissioning and support of measuring instruments, which should measure at the Sonnblick Observatory. Connection to inlet, indoor or outdoor operation, documentation and feedback with instrument owner.

Internship for students to become familiar with observatory operations and conduct their own small studies. Duration at least 2 weeks at the observatory.

TIME CONSTRAINTS: Winter, Summer

The Sonnblick Observatory has a cable car that covers 1,500 meters in altitude between the valley and the mountain. The cable car can be used for measuring profiles.

TIME CONSTRAINTS: No operation during thunderstorms

Data analysis and preparation of SBO data on specific issues, as well as graphical processing and reporting

TIME CONSTRAINTS: Depending on free resources and available lead time

Identification of possible source regions for air masses arriving at observatory based on atmospheric transport modelling based on meteorological forecast or analysis data from ECMWF

TIME CONSTRAINTS: Upon request depending on requirements (e.g. time period)

Identification of height-range above valley floor influenced by boundary layer air/free troposphere.

TIME CONSTRAINTS: Upon request depending on requirements (e.g. time period)

Conduction of wind Lidar measurements, data processing

TIME CONSTRAINTS: Depending on the availability of instrumentation

a) Hands-on training sessions on state of the art analytical instrumentation connected to ACD-C. 
b) Training on how to perform chamber experiments by experienced scientists.

ACD-C with its twin chamber setup is a unique research infrastructure to study VOC degradation mechanism, SOA formation processes, the chemical composition of the gas/ particle phase, and toxicological effects of formed SOA. The twin chamber is equipped with a broad online and offline instrumentation, including two SMPS, PTR-TOFMS, PTR-QMS, two CAPS, two sub-ppb level NO2 analysers, an AMS, a CI-APi-TOFMS to comprehensively characterize a wide variety of chamber processes. 
The Leipzig Biomass Burning Facility (LBBF) as additional part of ACD-C allows studies on primary emissions as well as the processing of the emitted smoke. A broad online and offline instrumentation at ACD-C enables highly sophisticated research on tropospheric multiphase processes to provide the heighest level of understanding on a molecular level.
 

LACIS-T is a unique infrastructure for investigating turbulence and its influences on cloud-microphysical processes. The investigations take place under well-controlled and reproducible flow, turbulence and thermodynamic (temperature, humidity) conditions. 
LACIS-T is equipped with high-end instrumentation for characterizing the prevailing thermodynamic, flow, turbulence and microphysical conditions. This includes measurements of temperature, mean water vapor concentration, flow velocity, turbulence intensity and dissipation rate as well as cloud particle size distributions.
 

Training on how to perform  experiments in humid turbulent flows by experienced scientists as well as hands-on training on high-end and state-of-the-art instrumentation for characterizing turbulent flows, as well as thermodynamic and aerosol particle and droplet microphysical properties.

-        Provision of data from simulation chamber experiments on study of atmospheric behaviour of biogenic and anthropogenic VOCs and semiVOCs, aerosols, product formation, etc. under nearly real conditions.
-        Access to a broad variety of instruments, both stablished and state-of-the art, including PTR-ToF-MS, CI-APi-ToFMS, etc.
-        Validation of photochemical models.
-        Support for planning and evaluation of data experiments.

TIME CONSTRAINTS: None. Coordination with other activities of the facility is needed. 

Testing / intercomparisons of new instruments (inorganic and organic, gas-phase and particulate pollutants)

TIME CONSTRAINTS: None in general. Coordination and planning in advance needed for the transportation of the facility.

It is a mobile facility.

Sources tested in the past include diesel and gasoline engines, wood stoves, pellet stoves, barbecues, etc. Both the primary emissions (after dilution) and their evolution during daytime and nighttime reactions are quantified. The user can supply the source to be studied.

TIME CONSTRAINTS: None in general. Coordination and planning in advance needed for the transportation of the facility.

It is a mobile facility.

Investigations of the evolution of ambient air in different environments. Potential for use of two chambers with changes of the conditions in one of the two with the addition of a pollutant or an oxidant.
