Our research intends to understand the tropospheric multiphase system. Model development is based on experimental work in the laboratory and in the field. Lab work utilises state-of-the-art physical and analytical chemistry methods to study gas phase, aqueous phase, organic phase, surface and, alltogether, multiphase phenomena. Field work aims to understand chemical processing and composition of tropospheric particles, clouds, fog and rain in the complex interplay of all compartments involved.

Field experiments

Kalibrierzentren

OGTAC-CC

The Atmospheric Chemistry Department (ACD) of TROPOS hosts the Organic Tracers and Aerosol Constituents - Calibration Centre (OGTAC-CC), which is the first calibration center for these class of compounds worldwide, providing a strong benefit to the aerosol community, as it harmonizes approaches for the chemical analysis of organic particulate constituents.
