The first is a set of isotopic data (d15N, d29, d30, and D30 values) collected on an ultrahigh resolution mass spectrometer. The second is a set of model parameters and results. Both were used to support the findings reported in L. Y. Yeung, S. Li, I. E. Kohl, J. A. Haslun, N. E. Ostrom, H. Hu, T. P. Fischer, E. A. Schauble, E. D. Young, Extreme enrichment in atmospheric 15N15N. Sci. Adv. 3, eaao6741 (2017). doi: 10.1126/sciadv.aao6741.Table descriptions follow below: table S1. Isotopic data for air samples and heated gases. table S2. Isotopic data for biological experiments. table S3. Data for electrolysis experiments. table S4. Reactions used in the model of the electrolysis experiments. table S5. Data for volcanic N2 samples and end members used to derive mixing fractions fRS and fmantle. table S6. Results from diffusion experiment for verifying instrumental accuracy.engAttribution-NonCommercial 3.0 United StatesDatasetNSF OCE-1533501NSF EAR-1349182NSF EAR-1348935NSF EAR-1530306BER DE-FC02-07ER64494
