摘要：A tethered balloon-based measurement was conducted to investigate vertical distribution of O-3 over Shanghai, China, during May of 2016. The time-series and diurnal variation of ground-level air pollutants (including O-3, NO, NO2 and VOCs) were analyzed systematically. By using TrajStat (a GIS-based software), the potential distant contributions of O-3 might come from East China Sea, and the Yangtze River Delta (YRD). Within 1000 m above ground, the average vertical profiles of O-3 exhibited obviously diurnal characteristics. Most of the NO and O-3 profiles measured on high-ozone days demonstrated anti-correlation. The launches on May 11, 2016 revealed that the Atmospheric Boundary Layer (ABL) and shifting of wind direction contributed to the peaks of O-3 at the upper altitude. A typical case of vertical mixing of O-3 was caught on May 18, 2016, when the ground-level O-3 was greatly influenced by the O-3 transported from high altitude (1500 in above sea level). The present study provides an important insight of the vertical distribution of O-3 over Eastern China, which implied that coupling effects of horizontal and vertical transportations on ground-level ozone should be investigated in future studies.
