论文摘要
EXOMARS痕量气轨道（TGO）于2016年3月发送到MARS，以寻找活动地质或生物生物过程的痕量诊断。我们报告了使用大气化学套件（ACS）中型（MIR）通道对火星臭氧（O3）在中红外范围内的光谱特征的首次观察，这是一种以太阳能掩盖模式运行的跨分散光谱仪，并具有对火星的任何遥感任务的最佳光谱分辨率。在2018年全球沙尘暴开始之前，在高北纬度（> 65n）上进行了臭氧的观察（LS = 163-193）。在夏季和冬季臭氧分布之间的快速过渡阶段，观察到的O3体积混合比为100-200 ppbv 20 km。这些量与紫外线范围内南极涡流边缘的过去观察结果一致。在3000-3060 cm-1处观察到的臭氧的光谱特征直接与甲烷（CH4）NU3 NU3振动振动带的光谱范围重叠，IT以及在同一区域中新发现的CO2带的光谱范围可能会干扰甲烷丰度的测量。
The ExoMars Trace Gas Orbiter (TGO) was sent to Mars in March 2016 to search for trace gases diagnostic of active geological or biogenic processes. We report the first observation of the spectral features of Martian ozone (O3) in the mid-infrared range using the Atmospheric Chemistry Suite (ACS) Mid-InfaRed (MIR) channel, a cross-dispersion spectrometer operating in solar occultation mode with the finest spectral resolution of any remote sensing mission to Mars. Observations of ozone were made at high northern latitudes (>65N) prior to the onset of the 2018 global dust storm (Ls = 163-193). During this fast transition phase between summer and winter ozone distribution, the O3 volume mixing ratio observed is 100-200 ppbv near 20 km. These amounts are consistent with past observations made at the edge of the southern polar vortex in the ultraviolet range. The observed spectral signature of ozone at 3000-3060 cm-1 directly overlaps with the spectral range of the methane (CH4) nu3 vibration-rotation band, and it, along with a newly discovered CO2 band in the same region, may interfere with measurements of methane abundance.
