Longitudinal distribution of O2 nightglow brightness observed by TIEMD/SABER satellite
Tóm tắt
The global distribution of 1.27 μm O2 nightglow brightness observed by the TIMED/SABER satellite has been investigated to find the longitudinal structures for different seasons and latitudes. The results show that the O2 airglow is dominated by wave 4 structure at latitudes between equator and 20°S/N in both hemispheres during most seasons. At mid-latitudes around 40°S/N, the wave 1 structure is observed for most seasons with a small contribution of wave 2 during the June solstice. A comparison of the O2 and OH nightglows shows similarity in their global distributions which can be attributed to their similar photochemical mechanisms.
