Nitrous oxide (N2O) is a potent greenhouse gas that, over the past several decades , has been increasing its forcing potential for atmospheric warming. An estimated 10% of all anthropogenically generated N2O is emitted from streams and rivers. These emissions are strongly correlated to ammonium and nitrate runoff from agricultural and industrial processes. However, not all impacted steams emit N2O. Reeder et al. (2018) showed that the flow of surface water and its interaction with stream bed morphology exerts control over the biological processes that are the primary source of (N2O) emissions from rivers and streams. A mathematical model that predicts which flowlines have the correct properties to produce and emit N2O is presented. The data provided in this contribution includes: (1) spatially distributed nitrous oxide measurements from a large-scale, long-term flume experiment, (2) KDO data used in the Tau_tilde transform, (3) data to calculate N2O fluxes through the hyporheic, (4) calculated residence times through the hyporheic and (5) compiled data for the averaged N2O/Tau profiles.
