The nitrate (NO 3 − ) isotopic composition δ 15 N-NO 3 − of polar ice cores has the potential to provide constraints on past ultraviolet (UV) radiation and thereby total column ozone (TCO), in addition to the oxidising capacity of the ancient atmosphere. However, understanding the transfer of reacti...
