Abstract :
The water vapor monitoring system (WVMS) is a ground based broad band microwave (22.235 GHz) radiometer that analyzes emission spectra from the mesosphere to determine water vapor mixing ratios. This paper emphasizes the technical details of the instrument, experimental techniques, comparison of alternate techniques, and especially accuracy and calibration issues.<>
