Intensity I, Stokes parameter Q, and degree of polarization P = Q/I in the O₂A band region. The top plots show high spectral resolution calculations with Δλ = 0.01 nm and the spectrum convolved with the instrument filter function. The bottom plots show the same spectral region calculated using the REPTRAN parameterization in three spectral resolutions (fine, medium, and coarse). The red line shows the REPTRAN calculation in coarse resolution convolved with the instrument filter function. For comparison, the data from Stam (2008) are also shown. The Lambertian surface albedo is 0.6.
