Abstract
The paper presents a new algorithm for constructing parameterizations of molecular absorption in the Earth's atmosphere, which takes into account the change in the atmospheric gas composition with altitude and has a number of other advantages, as well as a parametrization constructed using this algorithm in the frequency range from 10 to 2000 cm-1 in the altitude range from the Earth's surface to 76 km. A comparison of the results of calculations of the eigenvalue field of the Earth's atmosphere, carried out using this parametrization, with the results of reference calculations (line-by-line) shows that the presented parametrization has good accuracy in the lower and middle atmosphere in the absence of cloud layers and in the presence of cloud layers with a large optical thickness.
