Abstract

Ground‐based measurements of total ozone were made during the polar night from Arctic stations in the winters of 1987–88 and 1988–89. The measurements were made with automated Brewer ozone spectrophotometers using the moon as a light source. Data were obtained from Alert and Resolute in Canada for both winters and from Heiss Island, USSR, for the second winter. The method of measurement is briefly reviewed and data from the three stations are presented. The ground‐based total ozone measurements are compared with the integrated values derived from ozonesonde profiles.  相似文献

Presented are the results of studies dealing with the analysis of discrepancies in the data on total ozone measurements carried out using different instruments. The results of measurements with ground-based spectral (UV and visible) and filter instruments and spaceborne nadir scanning instruments are used as initial data. As a result of the analysis of relative systematic and random discrepancies, it is concluded that the data of filter instruments are of insufficient accuracy for diagnosing total ozone values. The analysis of linear trends revealed the presence of considerable differences in the data series obtained by spectral instruments. It is concluded that there is every reason to hope for obtaining the most homogeneous measurement data in Russia using the instruments operating in the Chappuis band.  相似文献

Abstract

Regular ground-based measurements of total ozone are available over the full Russian territory using M-124 filter ozonometers, Brewer spectrophotometers, and Système d'Analyse par Observation Zénithale (SAOZ) spectrometers in the Arctic region where these observations are essential for evaluating ozone loss in winter. Daily measurements are performed by three Brewer spectrophotometers; these are located in Kislovodsk (43.7°N, 42.7°E), Obninsk (55.1°N, 36.6°E), and Tomsk (56.5°N, 85.1°E). Two SAOZ spectrometers are deployed at the Arctic Circle in Salekhard (66.5°N, 66.7°E) and Zhigansk (66.8°N, 123.4°E). In addition, regular winter–spring ozonesonde soundings are carried out in Salekhard. Altogether, they have provided the unique measurements over the eastern Arctic required for characterizing ozone loss during each winter and will also monitor the anticipated ozone recovery following the reduction of chlorine and bromine ozone-depleting substances in the atmosphere.  相似文献
