We installed the Tunable Diode Laser Heterodyne Spectrometer (TDLHS) at Moshiri Observatory, Nagoya University in October, 1996. Measurement of Solar infrared spectra using TDLHS and Fourier-Transform Infrared Spectrometer (FTIR) were made for two weeks simultaneously. Absorption spectra of several trace molecules such as O3, N2O,HCl, HF,and HNO<@D23@>D2 were taken. Also ozonesonde measurements were conducted at Moshiri Observatory. Vertical profiles of volume mixing ratios (VMRs) of O3 were retrieved from these high-resolution solar spectra. The VMR profile retrieval is based on an iterative inversion algorithm, which utilizes line-by-line, layr-by-layr calculations. Eighty ozone vertical profiles were retrieved from the two spectral regions from 40 spectra and were compared with 17 ozonesonde measurements from a nearby station. Average differences between 18 and 34 km were less than (]SY.+-。[) 12%. The standard deviation of the average differences between 18 and 34 km were less than 20%. Effects of several different factors on errors of profile retrievals, such as initial guess, temperature profiles, and instrument line shape functions, were evaluated by numerical simulation. The estimated errors were extremely consistent with the observed errors between 18 and 34 km, suggesting that the FTIR was optically well adjusted. In general, it was found that retrieval of the O3 profile gives VMRs in an accuracy better than 40% at 14 km, improving to 10-15% between 18 and 30 km, with precision of 30% and 20% for these altitude ranges, respectively.

1996年10月，我们在名古屋大学Moshiri天文台安装了可调谐二极管激光外差光谱仪（TDLHS）。利用TDLHS和傅里叶变换红外光谱仪（FTIR）同时进行了为期两周的太阳红外光谱测量。测定了O3、N2O、HCl、HF、HNO<@D23@>D2等微量分子的吸收光谱。此外，在Moshiri天文台进行了臭氧探测仪测量。利用这些高分辨率太阳光谱反演了O3的体积混合比（VMRs）垂直剖面。VMR剖面检索基于迭代反演算法，该算法利用逐行、逐层计算。从40个光谱中提取了两个光谱区的80个臭氧垂直剖面，并与附近一个站的17个臭氧探空仪测量值进行了比较。18 ~ 34 km之间的平均差异小于（0.05±±）。(12%)。18 ~ 34 km平均差值的标准差小于20%。通过数值模拟，评估了初始猜测、温度曲线和仪器线形函数等因素对剖面反演误差的影响。估计误差与观测误差在18 ~ 34 km之间极为一致，表明FTIR进行了良好的光学调整。总的来说，我们发现O3剖面的反演使vmr在14公里的精度超过40%，在18至30公里之间提高到10-15%，在这些高度范围内的精度分别为30%和20%。
