Measurements of Atmosphere-Biosphere Exchange of Oxidized Nitrogen and Implications for the Chemistry of Atmospheric NO_x.

ABSTRACT: ConspectusThe atmosphere-biosphere exchange of nitrogen oxides plays a key role in determining the composition of reactive nitrogen in terrestrial vegetated environments. The emission of nitric oxide (NO) from soils is an important atmospheric source of reactive nitrogen. NO is rapidly interconverted with NO₂, making up the chemical family NO_x (NO_x ≡ NO₂ + NO). NO_x further reacts with the oxidation products of volatile organic compounds (VOCs) to form the functionalized nitrogen oxide groups acyl peroxynitrates (APNs = R(O)O₂NO₂) and alkyl nitrates (ANs = RONO₂). Both canopy-level field measurements and laboratory studies suggest that the absorption of nitrogen dioxide NO₂
