Abstract

Total column ozone (TCO) monitoring with the Dobson spectrophotometer no. 84 have been carried out at Belsk (51°50′, 20°47′), Poland, since 23 March 1963. TCO observations were made for various combinations of double wavelength pairs (AD, CD, CC′) and instrument settings (direct Sun, zenith blue, and zenith cloudy). In total, results of 115,736 manual observations were recorded in the period 1963–2019. The following metrics of the intraday TCO variability are examined: standard deviation divided by the mean value and the difference between the daily maximum and minimum divided by the mean value. The mean value, standard deviation, and 5th–95th percentile range for the intraday changes of the metrics are {1.6%, 0.8%, 2.5%} and {4.3%, 2.3%, 7.3%,}, respectively. To examine interday TCO variability, one-day changes of the metrics and the daily mean TCO are analysed. The corresponding statistics for one-day change of TCO are {−0.2%, 6.9%, 22.6%}. The short-term TCO variability changed only slightly (if ever) since the beginning of the ozone observations at Belsk.

1963年3月23日至2019年12月31日期间在波兰Belsk的Dobson分光光度计测量得出的总柱状臭氧的短期变化

摘要

使用Dobson分光光度计No.1监测总柱臭氧(TCO)。自1963年3月23日以来,已经在波兰的Belsk(51°50',20°47')进行了84次测量。对TCO进行了双波长对(AD,CD,CC')和仪器设置(直接太阳,天顶蓝和天顶多云)。在1963–2019年期间,总共记录了115,736例人工观测的结果。检查了日内TCO变异性的以下指标:标准偏差除以平均值,每日最大和最小值之间的差除以平均值。指标的日内变化的平均值,标准偏差和第5–95个百分点范围分别为{1.6%,0.8%,2.5%}和{4.3%,2.3%,7.3%,}。要检查日间总拥有成本的差异性,分析指标的一日变化和每日平均TCO。TCO一日变化的相应统计数据是{-0.2%,6.9%,22.6%}。自Belsk进行臭氧观测以来,短期TCO的变化仅发生了少许变化(如果有的话)。
