2019年中国典型区域-区域站VOCs组分观测数据

针对大气边界层内污染物传输、局地与区域大气污染相互作用规律等关键科学问题，基于车载DOAS走航观测技术，在中国东部（安徽省蚌埠市五河沱湖、湖北省荆州市监利、上海市青浦和天津市宁河）开展针对典型跨区域和跨国境输送通道的大气主要污染物NO2、SO2重点时段（夏季与冬季）加强观测，形成车载走航观测数据集。

To address key scientific issues including pollutant transport within the atmospheric boundary layer and the interaction laws between local and regional air pollution, intensive observations were conducted for major atmospheric pollutants NO₂ and SO₂ at typical trans-regional and cross-border transport corridors using vehicle-borne Differential Optical Absorption Spectroscopy (DOAS) traversing observation technology. The observations were carried out in eastern China at sites including Tuo Lake in Wuhe County, Bengbu City, Anhui Province; Jianli County, Jingzhou City, Hubei Province; Qingpu District, Shanghai; and Ninghe District, Tianjin, during key periods (summer and winter), thus forming the vehicle-borne traversing observation dataset.
