Data supporting "Regulatory Roles of Aerosol Liquid Water Content and Aerosol Acidity in Nitrate-Driven Air Pollution"

This dataset contains observational and processed data used to generate the figures and analyses in the manuscript submitted to Journal of Geophysical Research: Atmospheres. The data include PM, ions, NOx concentrations from 2020 to 2024, ISORROPIA result such as aerosol liquid water content (ALWC) and pH, ammonium availability index (J), and calculation results for the formation and consumption processes of NO3-.本数据集包含为提交至《地球物理研究杂志：大气卷》（Journal of Geophysical Research: Atmospheres）的手稿生成图表及开展分析所用的观测数据与经处理后数据。数据涵盖2020至2024年的颗粒物（Particulate Matter, PM）、离子、氮氧化物（Nitrogen Oxides, NOx）浓度数据，ISORROPIA模型结果（含气溶胶液态水含量（Aerosol Liquid Water Content, ALWC）、pH值、铵盐可用性指数（J）），以及硝酸根离子（Nitrate Ion, NO3-）生成与消耗过程的计算结果。
