LWP-90-DP150 Microwave Radiometer from Radiometer Physics GmbH

The LWP-90-DP150 instrument is a stand-alone system for automated weather-station use under nearly all environmental conditions. The total (integrated) amount liquid water in the vertical column above the radiometer is retrieved from the two-channel brightness temperature mesurements. There is only very limited information on water vapor (humidity) due to the lack of an water vapor line frequency.

Optical resolution: 2.0°nbsp;HPBW at 90 and 150 GHz (same field of view)
