The RPG ‐ HATPRO humidity and temperature profiling passive microwave radiometer measures a variety of atmospheric quantities with high temporal and spatial resolution. Due to its two 7 channel filterbank receivers it offers a high speed parallel detection of all 14 channels; for this reason, the RPG ‐ HATPRO is capable of performing fast Liquid Water Path sampling with 1 second time resolution and outstanding noise performance of < 2 g/m^2 RMS while simultaneously measuring full troposphere (up to 10 km altitude) profiles of temperature and humidity.

Retrieved Parameters: Humidity + temperature profiles (high precision in boundary layer), clouds, IWV, LWP, stability.
