This is the data supplement presented in Adcock et al. 2023 in which we present a 12-year time series of continuous atmospheric measurements of O2 and CO2 at the Weybourne Atmospheric Observatory in the United Kingdom between May 2010 and December 2021. These measurements are combined into the term Atmospheric Potential Oxygen (APO), a tracer that is conservative with respect to terrestrial biosphere processes. The measurement system was installed in October 2007, however, between October 2007 and May 2010 the system was still being developed and underwent major changes, leading to large gaps in the dataset and much of the data being of unknown quality and with calibration scale issues, therefore the data from this period have not been included. The measurements are ongoing. The CO2 is reported in ppm units and was measured using a non-dispersive infrared (NDIR) CO2 analyser from Siemens Corp., model Ultramat 6E. The O2 is reported as O2/N2 in per meg units and was measured using a dual lead fuel cell O2 analyser, Oxzilla from Sable Systems International Inc. APO is reported in per meg units and is calculated using a terrestrial biosphere exchange ratio of 1.10 mol mol-1 and a standard atmospheric mole fraction for O2 of 0.2095. We report hourly averages of 2 minute measurements. "NA" is used when there is no data. Gaps in the data are due to routine running of calibration cylinders, maintenance & removal of data with known technical issues. CO2 data were transferred onto the WMO NOAA X2019 calibration scale using Equation 6 in Hall et al., 2021, doi.org/10.5194/amt-14-3015-2021. O2 data are on the Scripps Institution of Oceanography (SIO) ‘S2’ scale that was used by SIO from April 1995 to August 2017.

本数据集由Adcock等人在2023年发表的补充材料中提供，其中展示了英国威伯恩大气观测站自2010年5月至2021年12月间连续12年的大气氧气（O2）和二氧化碳（CO2）测量数据系列。这些测量数据综合形成了大气潜在氧气（APO）这一术语，该指标在陆地生物圈过程中保持保守性。测量系统于2007年10月安装，然而，在2007年10月至2010年5月期间，系统仍在开发中，并经历了重大变革，导致数据集中存在大量空白，以及大量数据质量未知且存在校准尺度问题，因此该时期的数据未被纳入。测量工作持续进行中。二氧化碳以百万分之一（ppm）为单位报告，并使用西门子公司（Siemens Corp.）的非分散红外（NDIR）二氧化碳分析仪（型号Ultramat 6E）进行测量。氧气以氧气与氮气之比（O2/N2）的百万分之一为单位报告，并使用来自Sable Systems International Inc.的Oxzilla双铅燃料电池氧气分析仪进行测量。APO以百万分之一为单位报告，并使用陆地生物圈交换比1.10 mol mol-1和标准大气氧分压0.2095进行计算。我们报告了2分钟测量值的每小时平均值。“NA”用于表示无数据的情况。数据中的空白是由于常规运行校准气瓶、维护以及移除已知技术问题的数据所致。二氧化碳数据已根据Hall等人在2021年发表的方程6（doi.org/10.5194/amt-14-3015-2021）转移至世界气象组织（WMO）NOAA X2019校准尺度。氧气数据使用斯克里普斯海洋研究所（Scripps Institution of Oceanography, SIO）的‘S2’尺度，该尺度自1995年4月至2017年8月由SIO使用。
