High emissions of volatile organic compounds (VOCs) from the petrochemical industry and vehicle exhaust may contribute to high ozone formation potential (OFP) and secondary organic aerosol formation potential (SOAFP). In this study, the vertical profiles of VOCs were created for the southern Taiwan industrial city of Kaohsiung. Vertical air samples were collected up to 1000 m using an unmanned aerial vehicle (UAV). In Renwu District, VOC distribution was affected by the inversion layer up to 200 m height. Total VOCs (36-327 ppbv), OFP (66-831 ppbv) and SOAFP (0.12-5.55 ppbv) stratified by height were the highest values at 300 m. The VOCs originated from both local and long-distance transport sources. These findings can be integrated into Kaohsiung's future air quality improvement plans and serve as a reference for other industrialized areas worldwide.
挥发性有机化合物（VOCs）排放量高，来自石化工业和车辆尾气，可能导致高臭氧生成潜力（OFP）和二次有机气溶胶生成潜力（SOAFP）。在这项研究中，为台湾南部工业城市高雄创建了 VOC 的垂直分布廓线。使用无人机（UAV）采集了高达 1000 米的垂直空气样本。在仁武区，VOC 分布受逆温层影响，高度可达 200 米。总 VOCs（36-327 ppbv）、OFP（66-831 ppbv）和 SOAFP（0.12-5.55 ppbv）按高度分层，最高值出现在 300 米处。VOCs 既有本地来源，也有长距离传输来源。这些发现可以纳入高雄市未来的空气质量改善计划，并为全球其他工业化地区提供参考。
