Total column ozone (TCO) data from multiple satellite-based instruments have been combined to create a single near-global daily time series of ozone fields at 1.25^∘ longitude by 1^∘ latitude spanning the period 31 October 1978 to 31 December 2016. Comparisons against TCO measurements from the ground-based Dobson and Brewer spectrophotometer networks are used to remove offsets and drifts between the ground-based measurements and a subset of the satellite-based measurements. The corrected subset is then used as a basis for homogenizing the remaining data sets. The construction of this database improves on earlier versions of the database maintained first by the National Institute of Water and Atmospheric Research (NIWA) and now by Bodeker Scientific (BS), referred to as the NIWA-BS TCO database. The intention is for the NIWA-BS TCO database to serve as a climate data record for TCO, and to this end, the requirements for constructing climate data records, as detailed by GCOS (the Global Climate Observing System), have been followed as closely as possible.This new version includes a wider range of satellite-based instruments, uses updated sources of satellite data, extends the period covered, uses improved statistical methods to model the difference fields when homogenizing the data sets, and, perhaps most importantly, robustly tracks uncertainties from the source data sets through to the final climate data record which is now accompanied by associated uncertainty fields. Furthermore, a gap-free TCO database (referred to as the BS-filled TCO database) has been created and is documented in this paper. The utility of the NIWA-BS TCO database is demonstrated through an analysis of ozone trends from November 1978 to December 2016. Both databases are freely available for non-commercial purposes: the DOI for the NIWA-BS TCO database is https://doi.org/10.5281/zenodo.1346424 (Bodeker et al., 2018) and is available from https://zenodo.org/record/1346424. The DOI for the BS-filled TCO database is https://doi.org/10.5281/zenodo.3908787 (Bodeker et al., 2020) and is available from https://zenodo.org/record/3908787. In addition, both data sets are available from http://www.bodekerscientific.com/data/total-column-ozone (last access: June 2021).

全球总柱臭氧气候数据记录

来自多个基于卫星的仪器的总臭氧 (TCO) 数据已被结合，以在 1.25 ^∘经度 1 ^∘处创建一个接近全球的每日臭氧场时间序列纬度跨越 1978 年 10 月 31 日至 2016 年 12 月 31 日。与来自地面 Dobson 和 Brewer 分光光度计网络的 TCO 测量结果的比较用于消除地面测量结果与卫星测量子集之间的偏移和漂移。然后将校正后的子集用作均匀化剩余数据集的基础。该数据库的构建改进了该数据库的早期版本，该数据库最初由美国国家水和大气研究所 (NIWA) 维护，现在由 Bodeker Scientific (BS) 维护，称为 NIWA-BS TCO 数据库。目的是让 NIWA-BS TCO 数据库用作 TCO 的气候数据记录，为此，构建气候数据记录的要求由 GCOS（全球气候观测系统）详述，已尽可能紧密地遵循。这个新版本包括更广泛的基于卫星的仪器，使用更新的卫星数据源，延长覆盖的时间，在同质化数据集时使用改进的统计方法对差异场进行建模，以及，也许最重要的是，从源数据集到最终的气候数据记录，现在都伴随着相关的不确定性字段，稳健地跟踪不确定性。此外，还创建了一个无间隙 TCO 数据库（称为 BS 填充 TCO 数据库）并在本文中进行了记录。NIWA-BS TCO 数据库的实用性通过对 1978 年 11 月至 2016 年 12 月的臭氧趋势分析得到证明。两个数据库均可免费用于非商业目的：NIWA-BS TCO 数据库的 DOI 为 https://doi .org/10。（Bodeker 等人，2018 年），可从https://zenodo.org/record/1346424 获得。BS 填充的 TCO 数据库的 DOI 是 https://doi.org/10.5281/zenodo.3908787 (Bodeker et al., 2020)，可从https://zenodo.org/record/3908787 获得。此外，这两个数据集均可从http://www.bodekerscientific.com/data/total-column-ozone 获得（最后访问时间：2021 年 6 月）。
