Absorption of radiation by atmospheric gases is characterised by specific line transition structures. Spectrally high-resolved line-by-line (lbl) spectra of the respective optical depths may vary over several orders of magnitude. To avoid time-consuming lbl simulations spectral averaging is commonly applied to obtain an averaged layer optical depth as a basis for fine- and broad-band absorption parameterisations for input in band radiative transfer models. It is shown that various averaging approaches can be applied but leading to significantly differing optical depth spectra whereby the usually considered method of averaging the
layer transmissivity results in strong overestimations..
