FIG. 9.

A reflectance spectrum for a hazy Case B planet in the visible and NIR (a) and mid-IR (b) is presented with gases and the hydrocarbon haze removed to show where each spectral component interacts with radiation. The full spectrum is shown in black. Places where the black spectrum deviates from the colored spectra indicate where each gas or haze absorbs. For example, the green line shows a spectrum where CO₂ is omitted, and a strong CO₂ feature is present near 15 μm in (B) as shown by the deviation of the green spectrum from the black spectrum. At some wavelengths, gas and haze absorptions are complex to detangle because multiple species are absorbing: in these cases, the key on Fig. 8 will indicate which gases are the dominant absorbers in a region.
