JOYCE

joyce-qr-code

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.

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.
