“…Continuum absorption, on the other hand, decreases with temperature if gas partial pressures are held fixed with warming. The spectral features of our temperature‐dependent opacity deviation term compare closely to the “absorptivity effect” first discussed by Huang and Ramaswamy (
2007) (see their Figure 4), though we find a smaller magnitude of Δ T (likely in part because Huang and Ramaswamy (
2007) also include stratospheric warming). The nonlinear averaging deviation, Δ N ( ν ) (Figure 2a, purple), varies in sign across the spectrum, tracking the difference between the monochromatic brightness temperature
and the effective emission temperature T e .…”
