====== JOYCE ====== The **Jülich ObservatorY for Cloud Evolution** (JOYCE) is operated jointly by the [[http://www.geomet.uni-koeln.de/allgemein/home/|University of Cologne]], the [[https://www.fz-juelich.de/en|Research Centre Jülich]]. JOYCE is a national facility for Cloud Remote Sensing within the European Research Infrastructure [[https://www.actris.eu|ACTRIS]] since 2021. JOYCE was established in 2008 and was initially operated in the frame of the Transregional Collaborative Research Centre "Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling and Data Assimilation" ([[http://tr32new.uni-koeln.de/|TR32]]). Today, JOYCE is part of the Cloud and Precipitation Exploration Laboratory ([[http://cpex-lab.de|CPEX-LAB]]), a competence centre within the [[http://www.geoverbund-abcj.de/|Geoverbund ABC/J]]. {{:joyce_drone.jpg?600|}} {{:joyce_wolkenmessplatform01_bernahrd_pospichal.jpg?500|}}\\ //Left: Drone view of JOYCE platform, Right: View towards MIRA cloud radar with microwave radiometer in foreground// ===== Scientific Goals ===== JOYCE instrumentation aims to observe spatial and temporal variability of the atmospheric boundary layer as well as the water cycle. \\ 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 of Climate and Energy Systems - Troposphere (ICE-3) [[https://www.fz-juelich.de/en/ice/ice-3|IEK-8]] at the Research Centre Jülich which is embedded in an agricultural dominated landscape. * Latitude: 50°54'30.77" N = 50.908547°N * Longitude: 6°24'48.73" E = 6.413536°E * Altitude of the surroundings: 91 m asl * Altitude of JOYCE roof platform: 111 m asl (= 20 m above ground) * [[https://www.google.de/maps/place/50.9085833,6.4133333|Google maps link]] * [[http://atmos.meteo.uni-koeln.de/~hatpro/jue/img/ | Webcam]] * [[https://community.wmo.int/activity-areas/WIGOS/implementation-WIGOS/WIGOS-station-identifier | WIGOS ]]ID : 0-276-0-10508 ===== JOYCE Instruments ===== === Microwave radiometers === * [[https://obs.meteo.uni-koeln.de/doku.php?id=hatpro|Microwave Radiometer HATPRO]] - [[https://obs.meteo.uni-koeln.de/doku.php?id=tophat|TOPHAT]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=hatpro|Microwave Radiometer HATPRO]] - [[https://obs.meteo.uni-koeln.de/doku.php?id=joyhat|JOYHAT]] === Cloud radars === * [[https://obs.meteo.uni-koeln.de/doku.php?id=joyrad35|Cloud Radar JOYRAD-35 (Ka-Band)]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=joydurado|Cloud Radar JOYDURADO (Ka/W-Band)]] === Lidar/Ceilometer === * [[https://obs.meteo.uni-koeln.de/doku.php?id=ceilo|Ceilometer]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=chm15k|Ceilometer Jenoptik/Lufft CHM15k]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=ct25k|Ceilometer Vaisala CT25K]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=windlidar|Doppler wind lidar]] === Precipitation observations === * [[https://obs.meteo.uni-koeln.de/doku.php?id=mrr|Micro Rain Radar MRR]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=disdrometer|Disdrometer]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=pluvio|Pluviometer]] === Passive solar/infrared observations === * [[https://obs.meteo.uni-koeln.de/doku.php?id=aeri|Atmospheric Emitted Radiance Interferometer AERI]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=mfrsr|Multifilter Rotating Shadowband Radiometer MFRSR]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=tsi|Total Sky Imager TSI-AXIS]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=cimel|Sun photometer]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=radiation|Broadband radiation observations]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=pvm|Photovoltaic modules]] === Additional instrumentation === * CPEX-Lab Polarimetric X-Band Precipitation Radar [[https://www.ifgeo.uni-bonn.de/abteilungen/meteorologie/messdaten/radarbilder/aktuelle-bilder/sophienhoehe-juelich|Sophienhöhe]] and [[https://www.ifgeo.uni-bonn.de/abteilungen/meteorologie/messdaten/radarbilder/aktuelle-bilder/komposit-regenraten|composite]] with Bonn * [[https://www.fz-juelich.de/de/gs/ueber-uns/meteo|Meteorology at 120 m tower of FZ Jülich]] === Previous instrumentation === * [[https://obs.meteo.uni-koeln.de/doku.php?id=joyrad10|Cloud Radar JOYRAD-10 (X-Band)]] * [[https://obs.meteo.uni-koeln.de/doku.php?id=joyrad94|Cloud Radar JOYRAD-94 (W-Band)]] ===== 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.
