Inorganic particulate nitrate (p-NO), gaseous nitric acid (HNO) and nitrogen oxides (NO = NO + NO), as main atmospheric pollutants, have detrimental effects on human health and aquatic/terrestrial ecosystems. Referred to as the 'Third Pole' and the 'Water Tower of Asia', the Tibetan Plateau (TP) has attracted wide attention on its environmental changes. Here, we evaluated the oxidation processes of atmospheric nitrate as well as traced its potential sources by analyzing the isotopic compositions of nitrate (δN, δO, and ΔO) in the aerosols collected from the Mt.
