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).
The official site is http://joyce.cloud or http://www.geomet.uni-koeln.de/index.php?id=1082&L=1.
JOYCE instrumentation aims to observe spatial and temporal variability of atmospheric water cycle variables.
Specific goals are
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.
