{{ :joyce:logo_joyce_m.png?100|}} ====== JOYCE ====== {{:joyce:pano_juelich_640_ann.jpg|}} The **Jülich ObservatorY for Cloud Evolution** (JOYCE) is operated jointly by the [[http://www.geomet.uni-koeln.de/allgemein/home/|University of Cologne]], the [[http://www.fz-juelich.de|Research Centre Jülich]] and the Transregional Collaborative Research Centre "Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling and Data Assimilation" ([[http://www.tr32.de|TR32]]). ===== Quicklooks ===== * [[http://atmos.meteo.uni-koeln.de/~hatpro/dataBrowser/dataBrowser4.html?site=JOYCE&date=0&UpperLeft=Mira_Hatpo-Overview&UpperRight=Tophat_IWV-LWP&LowerRight=Tophat_cili&LowerLeft=Tophat_T-Prof|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 [[http://www.fz-juelich.de/gs/DE/UeberUns/Organisation/S-U/Meteorologie/wetter/wetterdaten_node.html|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 ===== [[http://maps.google.de/maps?f=q&hl=de&geocode=&q=50.908547,6.413537(HATPRO%40FZ+J%C3%BClich)&ie=UTF8&ll=50.908547,6.413537&spn=0.002496,0.004828&t=h&z=18&iwloc=addr|{{ :joyce:joyce_landuse.png?300}}]]

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 [[loehnert@meteo.uni-koeln.de|Dr. U. Löhnert]]. ===== Instruments ===== {{:joyce:radar.jpg?200|}} * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:aeri:aeri|Atmospheric Emitted Radiance Interferometer AERI]] * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:ceilo:ceilometer|Ceilometer CT25K]] * [[http://atmos.meteo.uni-koeln.de/~hatpro/jue/ceilo/jenopt/|Ceilometer CHM15k nimbus]] (raw data plots) * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:mira:mira|Cloud Radar MIRA]] * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:tophat:tophat|Microwave Radiometer HATPRO-TOPHAT]] * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:mrr:mrr|Micro Rain Radar MRR]] * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:sodar:sodar|Sodar]] * [[http://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=instruments:tsi:tsi|Total Sky Imager TSI]] * Polarimetric X-Band Radar [[http://www.meteo.uni-bonn.de/messdaten/radarbilder/aktuelle-bilder-1/sophienhoehe|Sophienhöhe]] and [[http://www.meteo.uni-bonn.de/messdaten/radarbilder/aktuelle-bilder-1/komposit|composite]] with Polarimetric X-Band Radar University of Bonn * [[http://aeronet.gsfc.nasa.gov/cgi-bin/type_one_station_opera_v2_new?site=FZJ-JOYCE&nachal=2&level=1&place_code=10|Sun Photometer]]
