Abstract
Summary form only given. An atmospheric line-by-line radiative transfer code has been used to model transmittance and radiance for the absorption bands of several gases of interest in remote sensing. The choice of line shape to account for effects such as the absorption contribution from the wings of distant lines, sub-Lorentzian line wing behavior, and the effect of rotational line coupling in Q-branches is discussed. Calculations have been performed to compare the line-by-line model results with spectra from high-resolution atmospheric experiments such as ATMOS. Rotational line coupling is clearly visible in this spectra in the CO2 15-μm region and introduces differences of around 20% in transmittance compared to calculations made assuming simple Voigt line profiles. The model has been used to assess the importance of line shape modeling for the CLAES spectrometer and ISAMS pressure modulator radiometer instruments aboard the Upper Atmosphere Research Satellite (UARS).
