The total column ozone (TCO₃) measurements by the Dobson spectrophotometer (serial no. 84) have been carried out at Belsk station (51^∘50^′ N, 20^∘47^′ E), Poland, since 23 March 1963. In total, ∼115 000 intraday manual observations were made by 31 December 2019. These observations were performed for different combinations of double wavelength pairs in the ultraviolet range and observation types, i.e., direct sun (DS), zenith blue (ZB), and zenith cloudy (ZC) depending on weather conditions. The long-term stability of the instrument was supported by frequent (almost every 4 years) intercomparisons with the world standard spectrophotometer. Trend analyses, based on the monthly and yearly averaged TCO₃, can be carried out without any additional corrections to the intraday values. To adjust these data to the Brewer spectrophotometer observations, which were also performed at Belsk, a procedure is proposed to account for less accurate Dobson observations under low solar elevation, presence of clouds, and the temperature dependence of ozone absorption. The adjusted time series shows that the Brewer–Dobson monthly averaged differences are in the range of about ±0.5 %. The intraday TCO₃ database, divided into three periods (1963–1979, 1980–1999, and 2000–2019), is freely available at https://doi.org/10.1594/PANGAEA.919378 (Rajewska-Więch et al., 2020).

贝尔斯克（波兰）多布森分光光度计在 1963-2019 年期间测量的总柱臭氧量：对布鲁尔分光光度计的均质化和调整

总计列臭氧（TCO ₃）由多布森分光光度计测量（序列号84）已经在Belsk站已进行了（51 ^∘ 50 ^'  N，20 ^∘ 47 ^'  E），波兰，1963年三月在总自23，～115 000在 2019 年 12 月 31 日之前进行了日内手动观测。 这些观测是针对紫外线范围和观测类型中双波长对的不同组合进行的，即直射太阳 (DS)、天顶蓝 (ZB) 和天顶多云 (ZC)，具体取决于关于天气情况。该仪器的长期稳定性得到了与世界标准分光光度计的频繁（几乎每 4 年）比对的支持。趋势分析，基于每月和每年的平均TCO ₃, 无需对日内值进行任何额外修正即可执行。为了将这些数据调整到也在贝尔斯克进行的布鲁尔分光光度计观测，提出了一种程序来解释低太阳高度、存在云和臭氧吸收的温度依赖性下不太准确的多布森观测。调整后的时间序列显示 Brewer-Dobson 月平均差异在大约±0.5  %的范围内。日内TCO ₃数据库分为三个时期（1963-1979、1980-1999 和 2000-2019），可在 https://doi.org/10.1594/PANGAEA.919378（Rajewska-Więch 等人， 2020）。
