We observed a strong increase in deseasonalized ozone at urban stations in the Tibetan Plateau from 2015 to 2019, far exceeding the trend at the baseline station Waliguan and the Tibetan Plateau average trend of four tropospheric ozone products. By combining multiple datasets and modeling approaches, we identified the main contributing factors as more frequent transport passing through the lower layers of high-emission regions and the increase in local and non-local anthropogenic emissions.
