Results of our modern Venus model. In the upper left panel, showing the temperature profiles, the dashed black line shows the empirical model by Hedin et al. (1983) and the dotted black line shows the daytime profiles shown in Fig. 9 of Gilli et al. (2017). In the upper right panel, showing the density profiles of several important species, the solid lines show the results of our model and the dotted lines show the profiles given by Hedin et al. (1983). The lower left panel shows the heating and cooling mechanisms for the neutral gas, and the lower right panel shows all of the heating mechanisms.
