A previously reported transmittance model for nitrogen dioxide in the two fundamental bands ν2 and ν3, plus the combination band ν1 + ν3, is now presented using upgraded synthetic spectra and measured data. The model consists of a well-established double-exponential function which approximates homogeneous path transmittance at 5-cm−1 intervals with a spectral resolution of 20 cm−1. Its parameters and other computational features are developed for direct compatibility with the widely used AFGL lowtran code. Transmittance calculations in the range from zero to unity deviate on the average ~0.84% from a combination of synthetic and measured spectra, which constitutes an improvement over the previously reported model.
