Instrument

MWR
Microwave Radiometer

Microwave radiometers (MWRs) are ground-based instruments manufactured by Radiometrics Corporation and operated by the Atmospheric Radiation Measurement (ARM) Research Facility. MWRs measure brightness temperature at 23.8 and 31.4 GHz to determine column amounts of water vapor and liquid water in the atmosphere. MWRs have a field of view (FOV) ranging from about 5.9 to 4.5 degrees, depending on the channel, and typically have a time resolution of 20 seconds for sky-view observations.
