In-Canopy Biogenic Volatile Organic Compounds Mixing Ratios at the Virginia Forest Lab

Two years (September 15th, 2019-September 14th, 2021) of biogenic volatile organic compound concentration data from within the canopy of a forest in Fluvanna County, Virginia. An associated manuscript is published in atmospheric chemistry and physics titled - "Measurement Report: Variability in the composition of biogenic volatile organic compounds in a southeastern US forest and their role in atmospheric reactivity". The doi for this manuscript is: 10.5194/acp-2021-416. The original version of this data set did not correct for when the data was sampled vs. when it was analyzed. The most recent version has been updated to reflect this and additional detail has been provided. Additionally, the calibration method for methacrolein and methyl vinyl ketone has been updated in this version of the data set. Given these changes, we ask that you use the most recent version. Additional manuscripts associated with this data include: 'Minor contributions of daytime monoterpenes are major contributors to atmospheric reactivity' which discusses diurnal and seasonal variability found within the data and 'An autonomous remotely operated gas chromatograph for chemically resolved monitoring of atmospheric volatile organic compounds' which outlines the instrument developed for data collection and compound integration. This will be the final update of this data set. Data collection is ongoing indefinitely, but future additions to the data set will be migrated to Dryad. Please email with any questions you may have regarding data collection or the data set.本数据集涵盖2019年9月15日至2021年9月14日共计两年的美国弗吉尼亚州弗卢万纳县某森林冠层内的生物源挥发性有机化合物（biogenic volatile organic compound）浓度监测数据。相关研究论文已发表于《大气化学与物理（Atmospheric Chemistry and Physics）》，题为《Measurement Report: Variability in the composition of biogenic volatile organic compounds in a southeastern US forest and their role in atmospheric reactivity》，该论文的DOI为10.5194/acp-2021-416。本数据集的初始版本未对数据采样与分析的时间差异进行校正，最新版本已针对该问题完成校正并补充了相关细节信息。此外，本数据集当前版本更新了甲基丙烯醛（methacrolein）与甲基乙烯基酮（methyl vinyl ketone）的校准方法。鉴于上述更新，恳请使用者采用本数据集的最新版本。本数据集关联的其他研究论文包括：其一为《Minor contributions of daytime monoterpenes are major contributors to atmospheric reactivity》，该论文探讨了数据中观测到的单萜类化合物（monoterpenes）的日变化与季节变化特征；其二为《An autonomous remotely operated gas chromatograph for chemically resolved monitoring of atmospheric volatile organic compounds》，该论文详细介绍了用于数据采集与化合物积分的自主远程操作气相色谱仪。本次更新为本数据集的最终一次更新。后续将持续开展数据采集工作，但新增数据将迁移至Dryad学术数据平台发布。若您对数据采集或本数据集有任何疑问，可通过邮件联系我们。
