A quick procedure is proposed for computing of molecular absorption by line—by—line technique, which includes the known up-to-date algorithms reducing computation time by employing nonuniform grid over wavelengths together with a developed criterion for spectral line selection. The selection is made by the magnitude of the optical depth and is most efficient for inhomogeneous atmospheric path as the number of lines decreases with height.
