OTHER_COMMENTS: Data are start and stop times for individual flask samples taken with Medusa. The Mean_UTC variable is the representative time of each sample as calculated with an averaging kernel. See Bent 2014 (PhD thesis, UCSD) for details. All pressure variables are measured in situ during sampling except for flask_pressure, which is the final pressure of the flask measured during analysis. In each flask the O2/N2 ratio and the Ar/N2 ratio are measured. When necessary a altitude-dependent fractionation correction is applied (O2_N2_corr). CO2 is extracted after CO2 and O2/N2 content analysis for later isotope analysis: d13-CO2, d18O-CO2, and radiocarbon (D14C). REVISION: R1 R1: updated R0: final data.
