Short summary

The lifetime of nitrogen oxides (NO_x) is evaluated by analysis of field measurements from the southeastern United States. At warm temperatures in the daytime boundary layer, NO_x interconverts rapidly with both PAN and alkyl and multifunctional nitrates (RONO₂), and the relevant lifetime is the combined lifetime of these three classes. We find that the production of RONO₂, followed by hydrolysis to produce nitric acid, is the dominant pathway for NO_x removal in an isoprene dominated forest.
