The W-band cloud radar (RPG-FMCW-94-SP-G1) member of the FRM4Radar network is a Frequency Modulated Continuous Wave (FMCW) Radar which delivers a calibrated Doppler spectrum of cloud droplets in a vertical range between 0.2 km … 15 km at a time resolution of 10 s. The radar point vertically and additionally equipped with a passive radiometric channel at 89-GHz that is sensible to cloud liquid water. Thus, the liquid water path (LWP) can be retrieved using the 89-GHz and by using the same antenna for the passive and active received signal a perfect beam overlap is accomplished.  Due to this additional feature, the Cloudnet algorithm can/will be operated in synergy with a ceilometer.
