ATom: Age of Air, ArN2 Ratio, and Trace Gases in Stratospheric Samples, 2009-2018

B. Birner, M. Chipperfield, E.J. Morgan & R.F. Keeling
This dataset provides calculated age of air (AoA) and the argon/nitrogen (Ar/N2) ratio (per meg) from stratospheric flask samples and simultaneous high frequency measurements of nitrous oxide (N2O), carbon dioxide (CO2), ozone (O3), methane (CH4), and carbon monoxide (CO) that have been compiled from three airborne projects. The trace gases were used to identify 235 flask samples with stratospheric influence collected by the Medusa Whole Air Sampler and to calculate AoA using a new N2O-AoA...
