Precise measurements are integral to understanding the biogeochemical processes that govern our planet. For example, when analysing changing concentrations of gases that make up Earth’s atmosphere, such as CO2, the concentrations, and/or rate of change of the measured gas is often very small. Therefore it is imperative to pursue excellent measurement capabilities with long term accuracies, in order to produce long term (decades) high accuracy records detailing the fate of trace gases.
