Short summary

We present the first simultaneous PAN and O₃ measurements from the central Tibetan Plateau. Both gases showed unique diurnal cycles with steep rises in the early morning and broader daytime platforms, which is attributed to the PBL evolution. Some high PAN and O₃ episodes were observed and caused either by long-range transport of pollutants from south Asia or by downward transport of air masses from the upper troposphere, indicating the dynamic impacts on tropospheric chemistry over the Tibet.
