通过与阿拉斯加Poker Flat（65.1°N, 147.5°W）多台仪器测量的剖面数据进行比较，验证了改进翼面大气光谱仪ii (ILAS-II) 1.4版本数据的有效性。将ILAS-II提供的O3和HNO3的高度分布与地基傅里叶变换红外光谱仪（FTS）测量的光谱进行了比较。ILAS-II和FTS在17-35 km高度范围内测量的O3和HNO3丰度在两次测量的精度范围内一致。ILAS-II在20 km以上（以下）测量到的O3体积混合比FTS测量结果低（高）10%。ILAS-II和FTS的HNO3值同意在17公里以上的10%以内。从费尔班克斯（64.8°N, 147.9°W）发射的电化学浓度电池（ECC）臭氧探测器获得的O3分布也与ILAS-II数据进行了比较。ILAS-II臭氧丰度与臭氧探测值一致。对比ILAS-II和瑞利激光雷达获得的中层和平流层上层温度数据表明，在60 (40)km处，ILAS-II获得的温度显著高于（低于）激光雷达。
[1] Version 1.4 data from the Improved Limb Atmospheric Spectrometer-II (ILAS-II) were validated through comparison with profile data measured by several instruments at Poker Flat (65.1°N, 147.5°W), Alaska. The height profiles of O3 and HNO3 provided by ILAS-II were compared with those retrieved from spectra measured by a ground-based Fourier transform infrared spectrometer (FTS). The O3 and HNO3 abundances measured by ILAS-II and FTS in the 17–35 km altitude range agreed within the precision of the two measurements. The O3 volume mixing ratios measured by ILAS-II above (below) 20 km were 10% lower (higher) than those from the FTS measurements. The HNO3 values from ILAS-II and FTS agreed to within 10% above 17 km. The O3 profiles obtained from electrochemical concentration cell (ECC) ozonesondes launched from Fairbanks (64.8°N, 147.9°W) were also compared to ILAS-II data. The ILAS-II ozone abundance agreed with the ozonesonde values. Comparison of mesospheric and upper stratospheric temperature data obtained by ILAS-II and Rayleigh lidar indicated that the temperature derived from ILAS-II was significantly higher (lower) than that from lidar at about 60 (40) km.
