RPG's profiling radiometers are mainly used to derive vertical profiles of atmospheric temperature and humidity (RPG-HATPRO). The infrared radiometer extension allows to cloud base height and ice cloud detection. The radiometer series covers high-resolution temperature profiling of the boundary layer and low-humidity applications. All models of the series provide accurate total amounts of atmospheric water vapour and cloud liquid cloud. RPG radiometers are stand-alone systems for automated weather-station use under nearly all environmental conditions.

Frequencies:

Two bands, 22-31 GHz (7 channel filter bank humidity profiler and LWP radiometer) and 51-58 GHz (7 channel filter bank temperature profiler)
