As the name of the working group already mentions, we exploit Observations in Meteorology to explore new meteorological observation systems or methods to improve our knowledge of the atmospheric structures involved dynamical and microphysical processes. One of our focuses is the observation of and in the Atmospheric Boundary Layer (ABL). These observations can help us shed light on the physical processes in the ABL, such as turbulent fluxes or cloud and precipitation formation. Also, we investigate the impact of these observational methods on short-term weather forecasts and high-resolution re-analyses.

The main focus of our working group is to use remote sensing instrumentation to profile the atmosphere. Together with standard weather and atmospheric radiation measurement equipment, the instruments form the Jülich Observatory for Cloud Evolution (JOYCE). They are located on top of one of the buildings of the Forschungszentrum Jülich.

The University of Cologne operates a set of active and passive remote sensing instruments. So we generate data to perform our research. But JOYCE delivers data to International Research Infrastructures such as ACTRIS (Aerosol, Cloud, and Trace-gases Research infrastructure; a EU Measurement and Research Infrastructure) or E-Profiel (European Measurement Network for Wind and Aerosol profilers). International collaborations are necessary to improve and develop data products, measurement standards, and quality control routines.
