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).
JOYCE instrumentation aims to observe spatial and temporal variability of atmospheric water cycle variables. Specific goals are

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.
