Abstract :
[en] Individual nadir and limb VIRTIS-M-IR at 1.27 μm show that the O2(a1∆) nightglow emission is highly variable. This variability is observed spatially, but also in term of intensity and altitude of the emitting layer over time. Apparent wind velocities have been deduced from the nadir observations, as well as the e-folding times. Limb observations show that an increase of the emitting layer altitude is observed near the cold collar region.
