JOYCE
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).
Quicklooks
- Quicklook browser of current and past JOYCE observations.
- Current quicklooks of the past 24h weather from the base of the 120m meteorological tower at the Research Center Jülich can be found here.
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
Location
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.

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.
