Overcoming spectroscopic challenges in direct problems of satellite sounding of the atmosphere

Abstract

In this work, we discuss possibilities for obtaining more information from atmospheric sounding with IR-spectroscopy methods by increasing the instrumental spectral resolution and using polarization measurements of the solar and thermal radiation. The disadvantages of the modern methods for calculating the molecular absorption spectra in both rigorous (line-by-line) and fast (based on k-distributions) models of atmospheric radiative transfer are shown. Approaches are suggested to eliminate these disadvantages.
