mwr3c > Microwave Radiometer, 3 ChannelInstrument Type(s) > Baseline • Guest

The microwave radiometer 3-channel (MWR3C) provides time-series measurements of brightness temperatures from three channels centered at 23.834, 30, and 89 GHz. These three channels are sensitive to the presence of liquid water and precipitable water vapor.
