[1] 在平流层变化探测网络 (NDSC) 的框架内，2003 年 2 月 12 日至 3 月 8 日，在挪威安德内斯的安多亚火箭靶场（北纬 69°，东经 16°）举行了一次地面天顶观测紫外可见光谱仪的比对活动。所选地点被归类为补充性 NDSC 地点。来自 7 个国家的 8 个小组参加了此次活动，重点是 NO 2 、BrO 和 OClO 斜柱的测量。第一份活动出版物主要关注 NO 2 斜柱的测量。活动期间调查了不同的分析标准。其中包括使用每个组选择的拟合参数来提供他们认为是优化的检索。还使用了对所有组施加的附加参数组，包括波长间隔、吸收截面和拟合物种。将每种仪器的结果与所选参考仪器的测量结果进行比较，参考仪器的选择基于回归分析和太阳天顶角残差检查相结合的技术。考虑到在整个活动期间获得的太阳天顶角在 75° 和 95° 之间的数据，对于 NO 2 的情况，在 425-450 nm 区域施加分析参数，所有仪器的一致性在 5% 以内。当在 400-418 nm 区域检索 NO 2 斜柱或使用每位研究者为其仪器优化的参数时，测量结果的一致性较差。
[1] Within the framework of the Network for the Detection of Stratospheric Change (NDSC), an intercomparison campaign of ground-based zenith-sky viewing UV-visible spectrometers was held at the Andoya Rocket Range (69°N, 16°E) at Andenes, Norway, from February 12 to March 8, 2003. The chosen site is classified as a complementary NDSC site. Eight groups from seven countries participated in the campaign which focused on the measurements of slant columns of NO 2 , BrO, and OClO. This first campaign publication concentrates on measurements of the NO 2 slant columns. Different analysis criteria were investigated during the campaign. These included the use of fitting parameters as chosen by each group to provide what they considered to be optimized retrievals. Additional sets of parameters, imposed for all the groups, were also used, including the wavelength interval, absorption cross sections, and species fitted. Each instrument's results were compared to the measurements of selected reference instruments, whose choice was based on a technique combining regression analysis and examination of the residuals with solar zenith angle. Considering the data obtained during the whole campaign for solar zenith angles between 75° and 95°, all instruments agreed within 5% in the case of NO 2 with imposed analysis parameters in the 425-450 nm region. Measurements agree less well when retrieving the NO 2 slant columns in the 400-418 nm region or when using parameters optimized by each investigator for their instrument.
