Abstract
In this work, we discuss the possibilities to obtain more information content from atmospheric IR sounding through an increase in the instruments’ spectral resolution and the use of the polarization measurements of solar and thermal radiation. The disadvantages of the modern methods for accounting the molecular absorption spectra in both rigorous and fast (based on k -distributions) atmospheric radiative transfer models are shown. The approaches to eliminate these disadvantages are suggested.
