Our atmospheric measurements around the globe show that nitrous oxide (N2O) is uniformly distributed and has an average concentration of 311 plusmnl; 2.6 p.p.b. This small atmospheric variability of N2O suggests an N2O residence time of greater than 20 years. Our atmospheric N2O measurements over a 3-year period starting from November 1975 can be interpreted to mean an essentially unchanging background of N2O. Oceanic data from the Pacific between 46° N and 40° S show a significant surface super-saturation (average surface saturation = 133%) and an average flux of 36 × 10-14 g (N2O)/cm2 s can be calculated. This oceanic flux when extrapolated to global waters suggests an oceanic N2O source of 20 to 30 Mt(N2O)/year (13 to 19 Mt(N)/year)*.DOI: 10.1111/j.2153-3490.1979.tb00910.x
