Continuous atmospheric O2 and CO2 data from Weybourne Atmospheric Observatory in the United Kingdom

Time series of continuous atmospheric measurements of O2 and CO2 at the Weybourne Atmospheric Observatory in the United Kingdom between May 2010 and December 2025. 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. We report hourly averages of 2-minute measurements. An hour must have at least 9 measurements or the hourly average is not included. The standard deviations are the hourly standard deviations of the 2-minute measurements. "NA" is used when there is no data. Gaps in the data are due to routine running of calibration cylinders, maintenance and 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) 2023 calibration scale.
