Short summary
In this study, we present the first report on the annual variation of stable oxygen isotope anomalies in nitrate (NO3−) collected from the urban area of Lhasa, on the Tibetan Plateau, China. Using a Bayesian isotope mixture model, we found that the relative contribution of the NO3 + volatile organic compound (VOC) pathway to NO3− formation in spring in Lhasa was several times higher than that in urban cities, highlighting the significant influence of VOCs transported from outside the Tibetan Plateau.
