a Barometric pressure in atmospheres (atm) corresponding to each of 28,112 float profiles. The barometric pressures displayed are the mean of ERA5 and NCEP reanalysis products that have been interpolated to the location and time of float profiles. b Air-sea nitrous oxide (N2O) pressure disequilibrium, \(\Delta p{N}_{2}O\), defined as the partial pressure of N2O in seawater (\(p{N}_{2}{O}_{{sw}}\)) minus the partial pressure N2O in the atmosphere (\(p{N}_{2}{O}_{{atm}}\)), such that positive values indicate \(p{N}_{2}{O}_{{sw}} > p{N}_{2}{O}_{{atm}}\). c Air-sea N2O flux in micromoles/meter squared/day (µmol/m2/day). Positive values indicate flux out of the water. In all subplots, points are scaled by the magnitude of air-sea N2O flux (a–c).
