Collaborative Research: Atmospheric measurements of O2/N2 ratio, CO2 concentration, and CO2 isotopes in support of the Arctic Observing Network
This project will support a continuation of time series measurements of atmospheric CO2 concentration, the stable isotopes of CO2, and the O2/N2 and Ar/N2 ratios of air samples collected at Arctic sampling stations. Measurements of O2/N2 ratio at Arctic sites, when also combined with measurements at...
