  "abstract": "The novel concept of quasi-correlated gas absorption spectra is introduced in this work for modeling radiative transfer in non-uniform gaseous paths. The quasi-correlation assumption is proposed as a generalization of the commonly used concept of correlated spectra and is developed to extend the limits in accuracy that are inherent in the correlated spectrum assumption. It is defined using the previously introduced Spectral Gamma Function, which characterizes the correlation between gas absorption spectra at different thermodynamic states. An application of the quasi-correlation concept is presented in several atmospheric remote sensing scenarios for calculating band-averaged transmissivities of non-uniform paths. Using the same number of gray gas intervals, the quasi-correlated approach significantly improves the accuracy of k-distribution methods in radiative transfer calculations for non-uniform paths, compared to the traditional correlated k-distribution (CKD) method.",
