Left column: pressure-temperature profiles from the cloudless GCM models (top, cloudless GCM with low T_int; bottom, cloudless GCM with high T_int; grey, profiles at all latitudes and longitudes and light blue, 1D profile from Wiser et al. 2025). The condensation curves of several important species are plotted as dashed lines. Right column: ADAM spectrum plotted with JWST observations in grey (top, emission spectra for cloudless GCM with low and high T_int showing significant overlap, indicating minimal sensitivity to internal heating in the terminator region, plotted along with 1D spectrum from Wiser et al. (2025); bottom, transmission spectra for cloudless GCM with low and high T_int showing significant overlap, indicating minimal sensitivity to internal heating in the terminator region).
