2018-2020年关中地区高塔站PM2.5化学组分（黑碳、水溶性离子数据、重金属元素）数据

本研究为构建关中空气质量多参数立体观测体系，通过三维立体布点，水平层面上依托关中大气环境地面监测站网，垂直层面选择在关中东、中和西部的代表区域建立 3 个高塔观测站。项目于2018-2 020年，在西安、咸阳和宝鸡分别建立了高塔超级观测站点，获得细颗粒物及前体物的高时间分辨率理化和光学在线表征。通过在线离子色谱获得PM2.5水溶性离子数据，黑碳仪 AE-33 获得黑碳浓度及不同波长下的吸收系数，在线重金属AMMS-100获得PM2.5重金属元素数据。

To establish a multi-parameter stereo observation system for air quality in the Guanzhong region, this study adopted a three-dimensional spatial layout: relying on the Guanzhong atmospheric environment ground monitoring network in the horizontal dimension, and establishing three tower observation stations in representative regions of the eastern, central and western Guanzhong in the vertical dimension. From 2018 to 2020, super tower observation stations were separately established in Xi'an, Xianyang and Baoji to acquire high-temporal-resolution physicochemical and optical online characterization data of fine particulate matter (PM2.5) and its precursors. Specifically, online ion chromatography was used to obtain water-soluble ionic data of PM2.5, the aethalometer AE-33 was applied to measure black carbon concentration and absorption coefficients at different wavelengths, and the online heavy metal analyzer AMMS-100 was utilized to collect heavy metal element data of PM2.5.
