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 vapor and cloud liquid cloud. RPG radiometers are stand-alone systems for automated weather-station use under nearly all environmental conditions. A variety of retrieval algorithms (custom designed and global standard algorithms) can be selected.
Meteorological observations, Numerical Weather Prediction (NWP), forecasting, now-casting, climate monitoring, aviation meteorology, astronomy, geodesy.
Two bands, 22-31 GHz (7 channel filter bank humidity profiler and LWP radiometer) and 51-58 GHz (7 channel filter bank temperature profiler)
Retrieved data types:
- vertical profiles of atmospheric temperature
- vertical profile of atmospheric humidty (relative and absolute humidity)
- Liquid Water Path (LWP)
- Integrated Water Vapor (IWV)
- wet delay
- dry delay
- stability indices
This system is very similar to the RPG-LWP liquid water path (two channel) radiometer: Only the receiver systems vary, housing and additional sensors are basically the same.
Different model types of profiling radiometers are available.
