Major influence of BrO on the NO x and nitrate budgets in the Arctic spring, inferred from Δ 17 O(NO 3 – ) measurements during ozone depletion events

The triple oxygen isotopic composition of atmospheric inorganic nitrate was measured in samples collected in the Arctic in springtime at Alert, Nunavut and Barrow, Alaska. The isotope anomaly of nitrate (Δ17O = δ17O – 0.52δ18O) was used to probe the influence of ozone (O3), bromine oxide (BrO), and...
