2017年大气环境站点大气颗粒物化学组分数据集

2017年贡嘎山、长白山、鼎湖山、阜康及兴隆等本底站点观测的大气颗粒物（粒径范围在0-100μm）水溶性离子质量浓度（μg/m^3），包含Na、NH4+、K、Mg、Ca、Cl、NO2-、NO3-和SO42-等化学组分。各化学组分质量浓度由粒径段范围在0-0.4μm，0.4-0.7μm， 0.7-1.1μm， 1.1-2.1μm， 2.1-3.3μm ，3.3-4.7μm ，4.7-5.8μm，5.8-9.0μm， 9.0-100μm颗粒物中相应组分质量浓度加和获得。

This dataset presents mass concentrations (μg/m³) of water-soluble ionic species in atmospheric particulate matter with a particle size range of 0–100 μm, which were observed at background monitoring stations including Gongga Mountain, Changbai Mountain, Dinghu Mountain, Fukang and Xinglong in 2017. The detected chemical components cover Na, NH4+, K, Mg, Ca, Cl, NO2⁻, NO3⁻ and SO4²⁻. The mass concentration of each chemical component is calculated by summing the mass concentrations of the corresponding species in particulate matter categorized into the following size intervals: 0–0.4 μm, 0.4–0.7 μm, 0.7–1.1 μm, 1.1–2.1 μm, 2.1–3.3 μm, 3.3–4.7 μm, 4.7–5.8 μm, 5.8–9.0 μm, and 9.0–100 μm.
