抽象的。加拿大SCISAT卫星上的ACE-FTS（大气化学实验-傅里叶变换光谱仪）仪器已经运行了12年多，能够得出许多NOy（N + NO + NO2+ NO3+ 2 × N2 O 5 + HNO 3 + HNO 4 + ClONO 2 + BrONO 2）种类的平流层分布图。ACE-FTS NO、NO2、HNO 3、N2 O 5和ClONO 2的2.2版以前已经过验证，本研究将这五种ACE-FTS产品的最新版本（v3.5）与来自其他卫星仪器（GOMOS、HALOE、MAESTRO、MIPAS、MLS、OSIRIS、POAM III、SAGE III、SCIAMACHY、SMILES和SMR）的空间和时间一致测量值进行了比较。对于每个ACE-FTS测量，使用光化学箱模型来模拟NOy物种的日变化，并将ACE-FTS测量缩放到同步测量的当地时间。所有五个物种的比较显示出良好的协议与相关的卫星测量。对于25-50 km高度范围内的NO，ACE-FTS通常与相关数据的一致性在-10%以内。在30-40 km处，NO2的仪器平均平均相对差异约为-10%，8-30 km处HNO 3的仪器平均相对差异在± 7%以内，21-34 km处当地早晨N2 O 5的仪器平均相对差异优于-7%，21-34 km处ClONO 2的仪器平均相对差异优于-8%。在可能的情况下，由于在比较当地时间和纬度的变化，在平均差异的变化也进行了讨论。
Abstract. The ACE-FTS (Atmospheric Chemistry Experiment – Fourier Transform Spectrometer) instrument on the Canadian SCISAT satellite, which has been in operation for over 12 years, has the capability of deriving stratospheric profiles of many of the NOy (N + NO + NO2+ NO3+ 2 × N2O5+ HNO3+ HNO4+ ClONO2+ BrONO2) species. Version 2.2 of ACE-FTS NO, NO2, HNO3, N2O5, and ClONO2 has previously been validated, and this study compares the most recent version (v3.5) of these five ACE-FTS products to spatially and temporally coincident measurements from other satellite instruments – GOMOS, HALOE, MAESTRO, MIPAS, MLS, OSIRIS, POAM III, SAGE III, SCIAMACHY, SMILES, and SMR. For each ACE-FTS measurement, a photochemical box model was used to simulate the diurnal variations of the NOy species and the ACE-FTS measurements were scaled to the local times of the coincident measurements. The comparisons for all five species show good agreement with correlative satellite measurements. For NO in the altitude range of 25–50 km, ACE-FTS typically agrees with correlative data to within −10 %. Instrument-averaged mean relative differences are approximately −10 % at 30–40 km for NO2, within ±7 % at 8–30 km for HNO3, better than −7 % at 21–34 km for local morning N2O5, and better than −8 % at 21–34 km for ClONO2. Where possible, the variations in the mean differences due to changes in the comparison local time and latitude are also discussed.
