Short summary
This paper presents an analysis of temperature and the trace gases PAN and O3 in the Asian Summer Monsoon (ASM) region. The positive PAN anomaly consisting of polluted air is confined vertically within the main ASM anticyclone, whereas a recently shed eddy exhibits enhanced PAN VMRs for 1 to 2 km above the thermal tropopause. This implies that eddy shedding provides a very rapid horizontal transport pathway of Asian pollution into the extratropical lowermost stratosphere.
