The Jülich ObservatorY for Cloud Evolution (JOYCE) is operated jointly by the University of Cologne, the Research Centre Jülich and the Transregional Collaborative Research Centre “Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling and Data Assimilation” (TR32).
Scientific Goals
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

Data availability
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.
