Multi-year high time resolution measurements of fine PM at 13 sites of the French Operational Network (CARA program)

These datasets correspond to long-term measurements of atmospheric aerosol components from Aerosol Chemical Speciation Monitor (ACSM) and multi-wavelength Aethalometer (AE33) instruments collected between 2015 and 2021 at 13 (sub)urban sites as part of the French CARA program. The datasets contain the mass concentrations of major chemical species within PM1, namely organic aerosols (OA), nitrate (NO3-), ammonium (NH4+), sulfate (SO42-), non-sea-salt chloride (Cl-), and equivalent black carbon (eBC). Rigorous quality control, technical validation, and environmental evaluation processes were applied, adhering to both the guidance from the French reference laboratory for air quality monitoring and the Aerosol, Clouds, and Trace gases Research Infrastructure (ACTRIS) standard operating procedures. These data are discussed in an article in submission, please cite it when using the data.本数据集涵盖法国CARA计划框架下，2015至2021年间在13个城郊站点，通过气溶胶化学组分监测仪（Aerosol Chemical Speciation Monitor, ACSM）与多波长黑碳仪（multi-wavelength Aethalometer, AE33）获取的大气气溶胶组分长期观测数据。 数据集包含PM1（粒径≤1μm细颗粒物）中主要化学组分的质量浓度信息，具体包括有机气溶胶（organic aerosols, OA）、硝酸盐（nitrate, NO3⁻）、铵（ammonium, NH4+）、硫酸盐（sulfate, SO4²⁻）、非海盐氯化物（non-sea-salt chloride, Cl⁻）以及等效黑碳（equivalent black carbon, eBC）。 本数据集严格执行了质量控制、技术验证与环境评估流程，完全契合法国空气质量监测参考实验室以及气溶胶、云与痕量气体研究基础设施（Aerosol, Clouds, and Trace gases Research Infrastructure, ACTRIS）的标准操作规范。 本数据集相关研究成果已投稿待刊，若使用该数据，请引用对应论文。
