Workshop on ground-based microwave radiometer operation and calibration

Date: Wednesday, 31 August, 2022 09:00 - Friday, 2 September, 2022 14:00

Venue: Forschungszentrum Jülich


This workshop on ground-based microwave radiometer observations is organized within the ACTRIS Centre for Cloud Remote Sensing (CCRES). The University of Cologne is hosting the microwave radiometer unit of CCRES which has the goal to ensure high-quality observations within the whole ACTRIS network. The workshop takes place at the Research Centre Jülich, where JOYCE (Jülich Observatory of Cloud Remote Sensing) is located. JOYCE is operated by the University of Cologne as an ACTRIS national facility for cloud remote sensing and is also part of the E-Profile program. 

This workshop is focused on all aspects of microwave radiometer operation, calibration, quality control and data processing. A special focus is given on network operation in ACTRIS and E-Profile. 



  • Microwave radiometry background (theory, retrieval development)
  • Practical aspects of MWR operation in networks (ACTRIS, E-Profile)
  • Calibration methods, hands-on calibration training
  • Presentation of the new ACTRIS MWR data processing (Python)
  • Overview of quality assurance and quality control methods
  • New developments in microwave radiometry



The workshop targets scientists and operators of microwave radiometers in networks, such as the ACTRIS Cloud Remote Sensing network (Cloudnet), E-Profile and others. The workshop is also open for interested people beyond this network, especially via the PROBE COST action.



Please send an e-mail until 26 June 2022 to actris-ccres-mwr(at) containing a short motivation letter with your main interests (max. 1 page).
Please provide following information: What are your main interests around microwave radiometry? Are you currently operating a microwave radiometer? Which networks are you participating?

The number of participants is limited! We will inform you about your participation by July 1st.

Some travel funding will be available via PROBE, please mention in your application whether you are interested in this funding. 




  • Time plan: Wednesday 31 August 2022 (morning) - Friday 2 September 2022 (early afternoon).
    • A more detailed time schedule will follow, but we will be quite flexible according to the weather.
