====== ACTRIS at University of Cologne ======

Within the [[https://www.actris.eu|ACTRIS research infrastructure]], the University of Cologne

  * operates JOYCE (Jülich Observatory for Cloud Evolution), an ACTRIS national facility (NF) for Cloud Remote Sensing \\
  * [[joyce|Link to the ACTRIS-NF JOYCE]]

  * and hosts a Topical centre unit on microwave radiometry of the [[https://www.actris.eu/topical-centre/ccres|Centre for Cloud Remote Sensing (CCRES)]].\\+
  * [[actris_cf|Link to ACTRIS-CF unit]]

===== ACTRIS organization and funding =====

ACTRIS was established as a ERIC (European Research Infrastructure consortium) in 2023, based on previous networks for aerosol, cloud and trace gas observations. 

The Federal Ministry of Education and Research (BMBF) is currently the implementation of ACTRIS in Germany: [[https://www.fona.de/en/measures/research-infrastructures/actris-d.php|Information on ACTRIS by BMBF/FONA]]. ACTRIS-D is coordinated by [[https://www.tropos.de/en/research/actris-d|TROPOS]]. Central facility funding is provided by ACTRIS-ERIC as well as the Federal Ministry for the Environment (BMUV). 

Further information on ACTRIS funding at University of Cologne can be found  [[https://verwaltung.uni-koeln.de/forschungsmanagement/content/large_scale_projects/federal_state_foundation_funding/actris_d/index_eng.html|here]]

//JOYCE platform//


The University of Cologne has operated the [[https://atmos.meteo.uni-koeln.de/ag_crewell/doku.php?id=sites:joyce|JOYCE observatory]] since 2008 and has been part of [[https://cloudnet.fmi.fi|Cloudnet]] since 2011, when all mandatory instruments for Cloudnet processing were installed.

[[https://cloudnet.fmi.fi/search/visualizations?site=juelich&product=classification|Link to current Cloudnet target classification]]

In the frame of the implementation of ACTRIS-D, the UoC received funding from BMBF and JOYCE was upgraded by a novel dual-frequency cloud radar and a Raman lidar.
