Observations show that the lower thermosphere of Mars (∼100–140 km) is up to 40 K colder than the current general circulation models (GCMs) can reproduce. Possible candidates for physical processes missing in the models are larger abundances of atomic oxygen facilitating stronger CO2 radiative cooling and thermal effects of gravity waves. Using two state‐of‐the‐art Martian GCMs, the Laboratoire de Météorologie Dynamique and Max Planck Institute models that self‐consistently cover the atmosphere…
