AWIPEV ist the French-German Arctic Research Base operated by the Alfred Wegener Institute for Polar and Marine Research (AWI) and the French Polar Institute Paul Emile Victor (IPEV). Within the Transregional Collaborative Research Centre TR 172 “ArctiC Amplification: Climate Relevant Atmospheric and SurfaCe Processes, and Feedback Mechanisms (AC)³” ((AC)³), the University of Cologne collaborated with AWI in the long-term observations at the Atmospheric Observatory.

JOYCE instrumentation aims to observe spatial and temporal variability of atmospheric water cycle variables.

Specific goals are

• to disentangle water vapor variations due to advection and to local surface influence
• to better understand the development of boundary layer clouds
• to analyse cloud radiation interaction
• to observe precipitation formation

Most instruments are located on the roof of the Institute for Energy and Climate Research - Troposphere IEK-8 at the Research Centre Jülich embedded in an agricultural dominated landscape.

JOYCE provides a number of resources, which characterize the thermodynamic state of the atmospheric column including vertical profiles of temperarture, humidity and cloud macro- and microphysical properties as well as the aerosol loading. The data is freely accessible for scientific and educational purposes and may be obtained through direct contact to Dr. U. Löhnert.
