Short summary
The vertical measurement of NOx and O3 was carried out on a movable carriage on a tower during a winter heavy-haze episode in urban Beijing, China. We found that pNO3- formation via N2O5 uptake was significant at high altitudes (e.g., > 150 m), which was supported by the lower total oxidant (NO2 + O3) level at high altitudes than at ground level. This study highlights the fact that pNO3- formation via N2O5 uptake may be an important source of pNO3- in the urban airshed during wintertime.
