Short summary
Improving air quality requires understanding of the atmospheric processes transforming nitrous oxides emitted by human activities into nitrates, an N form that may degrade natural ecosystems. Isotopes (∆17O, δ18O) are characterized in separate wet, particulate and gaseous nitrates for the first time. The gas ranges are distinct from those of the other nitrates, and the plume dynamics emerge as crucial in interpreting the results, which unravel key processes behind the distribution of nitrates.
