A set of proposals to overcome the crisis in Atmospheric Remote Sensing Technologies

Abstract

This chapter summarizes proposals to expand the capabilities of lidar measurements of the Earth’s atmosphere as a structural stratified medium with complex thermodynamics. The generalized structure of the revealed, statistically stable horizontal optical inhomogeneities of the surface layer and their dynamics are taken as an informative indicator of the thermodynamic stability of the atmosphere in the zone even beyond the limits of measurements. A special statistical method for analyzing the two identified structures is used. It is based on the separate fixation and statistical averaging of the intervals between local maxima and minima of the lidar backscattering signal and the analysis of the time dynamics of such an interval component of the signal during the night, under anticyclone conditions. It assumed that this approach makes it possible to identify certain statistically stable structures of atmospheric inhomogeneities of varying connectivity, depending on the overall thermodynamic stability of the atmosphere. In addition, a specific method is tested to search for emerging and temporarily stable anomalies of such a structure of atmospheric inhomogeneities, but associated with a violation of the thermodynamic stability of the atmosphere. Such a filtration method (identification of a certain anomaly against the background of an extended organized structure of inhomogeneities) showed high efficiency in model experiments compared to standard filtration methods.
