Short summary

Measurements of atmospheric O₂ can help constrain the carbon cycle processes and quantify fossil fuel CO₂ emissions; however, measurement of atmospheric O₂ is very challenging, and existing analysers are complex systems to build and maintain. We have tested a new O₂ analyser (Picarro Inc. G2207-i) in the laboratory and at Weybourne Atmospheric Observatory. We have found that the G2207-i does not perform as well as an existing O₂ analyser from Sable Systems Inc.
