Microwave Radiometer Profiler (MWRP) - IOP
Instrument Categories: Radiometric, Cloud Properties, Atmospheric Profiling
General Overview
The microwave radiometer profiler (MWRP) provides vertical profiles of temperature, humidity, and cloud liquid water content as a function of height or pressure at approximately 5-minute intervals for nearly all weather conditions. The profiles are derived from measurements of absolute microwave radiances (expressed as "brightness temperatures") obtained at twelve frequencies in the range of 22-30 GHz and 51-59 GHz. The data are useful for input to numerical weather forecast models and others that require continuous, high temporal resolution profiles. The microwave radiance measurements are useful for testing models of microwave radiation transfer used to derive the profiles.
