In this study, the new source of O(¹D) in the mesopause region due to the process OH$(\mathit{ν}â‰\yen \mathrm{5})+\mathrm{O}\left({}^{\mathrm{3}}\mathrm{P}\right)→\mathrm{OH}(\mathrm{0}≤\mathit{ν}{}^{′}≤\mathit{ν}-\mathrm{5})+\mathrm{O}({}^{\mathrm{1}}\mathrm{D}$) is applied to SABER data to estimate the nighttime O(¹D) distributions for the years 2003–2005. It is found that O(¹D) evolutions in these years are very similar to each other. Depending on the month, monthly averaged O(¹D) distributions show two to four maxima with values up to 340 cm^−3 which are localized in height (at ∼92–96 km) and latitude (at ∼20–40 and ∼60–80^∘ S, N). Annually averaged distributions in 2003–2005 have one weak maximum at ∼93 km and ∼65^∘ S with values of 150–160 cm^−3 and three pronounced maxima (with values up to 230 cm^−3) at ∼95 km and ∼35^∘ S, at ∼94 km and ∼40^∘ N and at ∼93 km and ∼65–75^∘ N, correspondingly. In general, there is slightly more O(¹D) in the Northern Hemisphere than in the Southern Hemisphere. The obtained results are a useful data set for subsequent estimation of nighttime O(¹D) influence on the chemistry of the mesopause region.

从SABER数据得出的更年期区域夜间O（¹ D）分布

在这项研究中，由于过程OH，在更年期区域产生了O（¹ D）的新来源$（\mathit{\sum }??\yen \mathrm{5}）+\mathrm{Ø}（{}^{\mathrm{3}}\mathrm{P}）一种？？？？\mathrm{哦}（\mathrm{0}??\mathit{\sum }{}^{′}??\mathit{\sum }--\mathrm{5}）+\mathrm{Ø}（{}^{\mathrm{1个}}\mathrm{d}$）应用于SABER数据，以估算2003–2005年的夜间O（¹ D）分布。发现这些年来的O（¹ D）演化非常相似。根据月份，月平均O（¹ D）分布显示2到4个最大值，其值最大为340？cm ^？3，这些值位于高度（？92 ????）。 96A ????公里）和纬度（在â??¼20 â???? 40和一个？？¼60 â???? 80 ^â???? â????
