In this paper, we consider the peculiarities of using the microwave radiometry method for remote sensing of the thermal stratification of the high layers of the atmosphere: the stratosphere and the lower mesosphere in comparison with other high-altitude layers, the troposphere and the atmospheric boundary layer. Such peculiarities are a special choice of spectral channels and bandwidths, the use of limb geometry of measurements along with the nadir in satellite instruments, as well as taking into account the influence of the Zeeman effect. Characteristics for first-generation satellite microwave sounders that measure temperature profiles up to an altitude of 30 km, as well as for more modern ground-based and satellite instruments, the sounding altitude of which reaches 50 km with a nadir-measurement geometry and 100 km with a limb one, are given. The results obtained in experiments with high-altitude balloons and using experimental setups for measuring the absorption coefficient of molecular oxygen at nearly 60 GHz are presented. The capabilities of ground-based instruments for microwave remote sensing of the stratosphere temperature and the results of complex comparisons are also analyzed. [ABSTRACT FROM AUTHOR] |
