中国第36次南极科学考察长城站大气气溶胶阴阳离子分析数据

极区受人为污染干扰小，对环境的响应敏感，是研究和明确气溶胶来源、全球传输规律及其环境影响的最佳区域。开展极区气溶胶研究不仅能掌握气溶胶的背景特征，了解南极自然环境变迁；更重要的是掌握人为活动对南极生态环境的扰动程度，揭示海洋大气气溶胶排放特征及其在全球气候变化中的作用。
本数据为南极长城站考察大气气溶胶阴阳离子分析数据，采样时间范围为2020年1月5日至2021年3月1日， 采样器型号(Device Type)为EDPL5000型，调查要素包括Na^+^、NH~4~^+^、K^+^、Mg^2+^、Ca^2+^、F^-^、MSA^-^、Cl^-^、NO~2~^-^、Br^-^ 、SO~4~^2-^、NO~3~^-^、HPO~4~^2-^等。

Polar regions, with minimal anthropogenic pollution interference and sensitive environmental responses, are optimal areas for researching and clarifying the sources of aerosols, global transport patterns, and their environmental impacts. Conducting polar aerosol research not only helps us grasp the background characteristics of aerosols and understand the changes in Antarctica's natural environment; more importantly, it enables us to master the degree of disturbance that human activities have caused to the Antarctic ecological environment, and reveal the emission characteristics of marine atmospheric aerosols and their role in global climate change.
This dataset contains analytical data of atmospheric aerosol anions and cations collected during the Great Wall Station survey in Antarctica. The sampling period spans from January 5, 2020 to March 1, 2021. The sampler model (Device Type) is EDPL5000, and the investigated parameters include Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺, F⁻, MSA⁻, Cl⁻, NO₂⁻, Br⁻, SO₄²⁻, NO₃⁻, HPO₄²⁻, etc.
