Ground-based microwave radiometric observations of atmospheric geopotential height fluctuations
Abstract
A ground-based, zenith viewing microwave radiometer was designed to measure precipitable water vapor, cloud liquid, and temperature profiles. It has two moisture-sensing channels and four temperature-sounding channels. Data are used to derive geopotential heights and thicknesses from the surface (830 mb) to 300 mb. Time series and spectra of directly measured and inferred quantities are analyzed for three meteorological situations: a period of unusual calm, a frontal passage, and a wave event. Comparisons of these data with various sources of ground truth, including radiosondes, aircraft, satellite cloud observations, and arrays of microbarographs, show excellent agreement.
