Figure 2. Synthetic planet atmosphere and spectrum. Top left: model temperature–pressure profile. The solid curve is the temperature profile and the dashed curve is the averaged thermal emission contribution function, or where the emission in the atmosphere is coming from. The temperature profile is constructed using Equations (13)–(16) and the parameters in Table 1. Top right: thermal emission contribution function. This plot shows where the emission is coming from as a function of wavelength, smoothed to a resolution of 0.05 μm. Red corresponds to the peak of the thermal emission weighting functions, where the optical depth is unity, and blue represents zero emission. Most emission emanates between a few bars and 0.01 bars with deeper layers probed by shorter wavelengths. Bottom left: resulting spectrum smoothed to a resolution of 0.05 μm. Blackbodies for the hottest, coolest, and average temperatures are shown. The dotted curves at the bottom are the filter profiles for typical photometric observations. Bottom right: gas Jacobian generate from Equation (9). This plot shows the sensitivity of the flux contrast as a function of wavelength to the various absorbers (the units are arbitrary but consistent).
