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.

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.
 

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.
 

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.
