Radiometer Physics GmbH (RPG)

RPG manufactures a wide range of instruments for remote sensing of the earth’s atmosphere and ocean / land surface, both ground based and airborne. The wide field of meteorological applications is covered by tropospheric temperature and humidity profilers, water vapor and cloud liquid radiometers, systems for atmospheric attenuation or wet / dry delay measurements (VLBI) and atmospheric Tau measurements (e.g. radio astronomy site characterizations). Another group of instruments offers dual polarization capabilities which are useful in applications like soil moisture or ocean salinity determination and cloud / rain liquid water discrimination. RPG’s spectrum of active instruments include microwave scintillation transmit-receive systems for ground latent heat flux monitoring as well as W-band cloud radars.
