Improving atmospheric path attenuation estimates for radio propagation applications by microwave radiometric profiling

Ground-based microwave radiometer (MWR) observations of downwelling brightness temperature (span classCombining double low line"inline-formula") are commonly used to estimate atmospheric attenuation at relative transparent channelsfor radio propagation and telecommunication purposes. The atmospheric attenuation is derived from span classCombining double low line"inline-formula"span by inverting the radiative transfer equation with a priori knowledge of the mean radiating temperature (
