We present the first observations of the oxygen-17 excess of atmospheric nitrate (Δ17O(NO−3)) collected in Beijing haze to reveal the relative importance of different nitrate formation pathways. We found that nocturnal pathways (N2O5 + H2O/Cl– and NO3 + HC) dominated nitrate production during polluted days (PM2.5 ≥ 75 μg m–3), with a mean possible fraction of 56–97 %.
We present the first observations of the oxygen-17 excess of atmospheric nitrate (Δ17O(NO−3))...
