Abstract

The University of Massachusetts Microwave Remote Sensing Laboratory (MIRSL) has developed a K-band spectral radiometer (KSR) capable of profiling atmospheric water vapor. The KSR system takes advantage of pressure broadening of the atmospheric emission spectra to measure the spatial distribution of water vapor. MIRSL´s spectral radiometer samples the atmospheric emission spectra at multiple frequencies near the 22.235 GHz resonance line. The authors describe the system and its operation.
