| Summary: | waves that propagate from the lower atmosphere and modified by the in situ heating caused by the absorption of near-IR radiation by CO 2. These processes are of key importance for our understanding of the upper atmosphere dynamics (and thus for future aeroassistance manoeuver, for instance), but they remain poorly understood: Numerical simulations results are model-dependent (25), and few observations are available. Within this context, the NO emission process identified here provides a powerful way to constrain GCM model behavior above 60 km in conjunction with spacecraft drag measurements (26). In particular, the GCM (25) predicts that, during the opposite season, the Hadley circulation globally extends to the polar regions because of the stronger solar forcing near perihelion and a dustier atmosphere. This circulation creates a downward flow above the high northern latitudes in the polar night, which is predicted to be about several times stronger than that during the southern winter. We should expect accordingly a much more intense NO emission |
