Continuous measurements of atmospheric carbon dioxide (CO2) and oxygen (O2) at Heathfield Tower 2021-onwards
Abstract
Continuous measurements of atmospheric carbon dioxide (CO2) and oxygen (O2) made at Heathfield Tower, East Sussex, UK.
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. These CO2 and O2 measurements were then combined to calculate Atmospheric Potential Oxygen (APO) in units of per meg.
The measurement system was installed in June 2021 and measurements are ongoing. Data are reported at 2-minute intervals. Gaps in the data are due to routine running of calibration cylinders, maintenance, and removal of data with known technical issues. CO2 data are on the WMO NOAA X2019 calibration scale and O2 data are on the Scripps Institution of Oceanography (SIO) 2023 calibration scale.
This dataset was originally part of the DARE-UK (Detection and Attribution of Regional greenhouse gas Emissions in the UK) project.
