<p><strong>Abstract.</strong> Quantifying the impact of rotational-Raman scattering (RRS) on the O<sub>2</sub> A- and B-bands is important as these bands can be used for cloud and aerosol characterization for trace-gas retrievals including CO<sub>2</sub> and CH<sub>4</sub>. In this paper, we simulate the spectral effects of RRS for various viewing geometries and instruments with different spectral resolutions. We also examine how aerosols affect the amount of RRS filling-in. We show that the

For comparison, we also compare and contrast the spectral signatures of RRS with those of terrestrial chlorophyll fluorescence.</p>
