Cloud radar JOYRAD-10 installed at Jülich


JOYRAD-10 is a vertically pointing X-Band Doppler cloud radar MIRA-10 manufactured by METEK GmbH. It is located at the Forschungszentrum Jülich as part of JOYCE. It has been installed as part of the Emmy-Noether research group OPTIMICE led by Stefan Kneifel in order to perform triple-frequency radar observations in combination with Ka- and W-Band radars.

Measurement modes

  • Vertically pointing observations with integration times up to 1 seconds.

JOYCE-CF Standard Operation Procedures

  • Standard measurement mode is vertically pointing, 2 second integration time

Calibrations and data quality assurance procedures

  • Check with co-located disdrometer to find out reflectivity offsets
  • Consistency check with other cloud radars
