mwrhf > Microwave Radiometer - High FrequencyInstrument Type(s) > Baseline

The microwave radiometer-high frequency (MWRHF) provides time-series measurements of brightness temperatures from two channels centered at 90 and 150 GHz. These two channels are sensitive to the presence of liquid water and precipitable water vapor.
