Atmospheric GHG data product (o2, o2_stdev, co2, co2_stdev) from Heathfield (100.0 m)

Continuous measurements of atmospheric carbon dioxide (CO2) and oxygen (O2) made at Heathfield Tower. The measurement system was installed in June 2021 and 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. 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.
