Seasonal Shifts in Nitrogen Isotope Fractionation Regimes in the Leighton Cycle

Abstract Nitrogen isotopes are used to trace nitrogen oxides (NO x = nitric oxide (NO) + nitrogen dioxide (NO 2 )) emissions and nitrate formation, but their interpretation depends on isotope redistribution during NO−NO 2 cycling. A key uncertainty is whether this partitioning is...
