Abstract
A radiometer system detects naturally occurring atmospheric microwave radiation in three bands at approximately 20, 30, and 90 GHz. Signals representing radiation intensity at each of these bands is converted into a brightness temperature and used as a system input to a processing system that yields system outputs including the atmospheric ice water path, liquid water path, and water vapor content. A parameterized radiative transfer model is used to quantify radiation emanating from the atmosphere. The applied signal processing technique provides measurement of the total ice column in the atmosphere, and simultaneously provides accurate measurement of water vapor and liquid water. A calibration technique enhances the accuracy of ice detection measurements by correcting for the effects of absorptive atmospheric components, such as water vapor and liquid water.
