Night O2 (a1Δg) airglow spatial distribution and temporal behavior on Venus based on SPICAV IR/VEx nadir dataset
Montmessin, F.; Fedorova, A.; Korablev, O. +6 more
The infrared O2 (a1Δg) airglow driven by the subsolar to antisolar circulation occurs between two global circulation regimes on Venus: the zonal super-rotation below 90 km and the subsolar to antisolar circulation over 120 km. Here we report the complete global results of SPICAV IR/Venus Express observations of O

This study combines the observations of the Venus Express Venus Radio science experiment (VeRa), Mars Express Mars Radio Science experiment (MaRS), and MAVEN Radio Occultation Science Experiment (ROSE) at Venus and Mars with proxies for environmental parameters, insolation and solar wind characteristics to compare the effects of individual drivers…
