Short summary

The MARGA instrument is a powerful research tool for investigating atmospheric chemistry and the exchange of gases and particles between the atmosphere and biosphere. Our study examines the operating characteristics of the instrument with a focus on the software used to calculate air concentrations. We show that more accurate measurements may be obtained by calibrating the instrument with a range of standards in addition to the single internal standard used in online concentration calculations.
