The study of the coupling between the lower and the upper atmosphere has been hindered by the lack of continuous temperature measurements covering the whole atmosphere from the surface to the exobase. Thus, a large fraction of our knowledge on the topic relies on Global Climate Models (GCM). Here we combine temperature measurements from different instruments on board the ExoMars TGO, MAVEN, and Mars Express missions to cover altitudes from 50 to 250 km. The combined measurements are then used to validate the predictions of the Mars-PCM, a ground-to-exobase GCM. The comparison with the GCM also allows identifying potential biases and differences between datasets. We will pay special attention to the local time variation of temperatures, affected by local heating processes and by propagating tides, which previous studies have shown not to be well captured by M-PCM, at least at the mesopause.
