Measurement report: 30 years of monitoring aromatic hydrocarbons (BTEX) at a suburban site in Europe

Data for the paper "Le Bras, Z.; Rubli, P.; Hueglin, C and Reimann, S.: Measurement report: 30 years of monitoring aromatic hydrocarbons (BTEX) at a suburban site in Europe, ACP. [preprint], https://doi.org/10.5194/egusphere-2025-3241, in review, 2025." Dataset summaryThese datasets contain monthly benzene, toluene, ethylbenzene and xylenes (BTEX) concentrations measured in ambient air at different Swiss monitoring stations: Dübendorf (DUE; 1994-2024), Zürich-Kaserne (ZUE, 2005-2024), Bern-Bollwerk (BER, 2011-2023) and Beromünster (BRM, 2018-2024). At DUE and BER, only BTEX are monitored using a gas chromatography photoionisation detector (GC-PID) while at ZUE and BRM, gas chromatography coupled with two flame ionization detectors (GC-FIDs) are used. Additionally, the dataset containing yearly (O)VOCs concentrations measured in ZUE has been included to support the BTEX monitoring in DUE. The (O)VOCs measurement are conducted according to ACTRIS CiGas guidelines. All the (O)VOC and BTEX concentrations are indicated in ppt. Data originThe data were originally uploaded to EBAS Database and are available at 1-hour resolution here: https://ebas-data.nilu.no/. The data are yearly checked upon submission to EBAS. Further details on the stations, sampling and instruments are further indicated in EBAS Database.本数据集对应论文：Le Bras, Z.; Rubli, P.; Hueglin, C. 与 Reimann, S.：《测量报告：欧洲城郊站点30年芳香烃（BTEX）监测》，ACP，[预印本]，https://doi.org/10.5194/egusphere-2025-3241，待审稿，2025年。 数据集概况：本数据集包含瑞士多个监测站点测得的环境空气中芳香烃（BTEX，即苯、甲苯、乙苯与二甲苯）的月均浓度数据，涉及站点分别为迪本多夫站（Dübendorf, DUE；1994-2024年）、苏黎世军营站（Zürich-Kaserne, ZUE；2005-2024年）、伯尔尼鲍尔沃克站（Bern-Bollwerk, BER；2011-2023年）以及贝罗明斯特站（Beromünster, BRM；2018-2024年）。其中迪本多夫站与伯尔尼鲍尔沃克站仅采用气相色谱光离子化检测器（gas chromatography photoionisation detector, GC-PID）开展BTEX监测；苏黎世军营站与贝罗明斯特站则使用配备双火焰离子化检测器的气相色谱系统（gas chromatography coupled with two flame ionization detectors, GC-FIDs）进行检测。此外，本数据集还纳入了苏黎世军营站测得的年际含氧挥发性有机物（(O)VOCs）浓度数据，用于辅助迪本多夫站的BTEX监测工作。该(O)VOCs监测工作严格遵循ACTRIS CiGas指南开展。所有含氧挥发性有机物与BTEX浓度的计量单位均为ppt。 数据来源：本数据集原始上传至EBAS数据库，原始数据的时间分辨率为1小时，可通过以下链接获取：https://ebas-data.nilu.no/。所有提交至EBAS的数据集每年均会接受合规性核查。关于监测站点、采样流程与仪器设备的更多详细信息，请查阅EBAS数据库。
