Dataset: Strong isoprene emission response to temperature in tundra vegetation

Dataset used in the article "Strong isoprene emission response to temperature in tundra vegetation" published in the journal Proceedings of the National Academy of Sciences of the USA 119: e2118014119 https://doi.org/10.1073/pnas.2118014119 The tab-delimited file contains direct surface-atmosphere isoprene fluxes, measured every 30-minutes by Eddy Covariance with a Proton Transfer Reaction -Time of Flight- Mass Spectrometer (PTR-ToF-MS) during the whole growing season at two different tundra sites in Scandinavia (near Abisko, Sweden in 2018, and near Finse, Norway during 2019). It also contains the MEGANv2.1 biogenic model predicted isoprene emissions for the same periods and sites. In addition, air temperature, vegetation surface temperature, and photosynthetic photon flux density (PPFD) measured at the sites are also reported, together with their past 24h and 240h averages (needed to run the MEGAN simulation accounting for the recent past environmental conditions).

本数据集对应发表于《美国国家科学院院刊》(Proceedings of the National Academy of Sciences of the USA) 119卷:e2118014119的论文《苔原植被对温度的强异戊二烯排放响应》(Strong isoprene emission response to temperature in tundra vegetation)，DOI: 10.1073/pnas.2118014119。该制表符分隔文件包含直接地表-大气异戊二烯通量数据：于整个生长季在斯堪的纳维亚的两处苔原站点采集，其中2018年采样于瑞典阿比斯库附近站点，2019年采样于挪威芬瑟附近站点，通量数据通过涡度相关法（Eddy Covariance）搭配质子转移反应-飞行时间质谱仪（PTR-ToF-MS）以每30分钟一次的频率获取。此外，文件还包含同期同站点的MEGANv2.1生物源模型预测异戊二烯排放量。同时记录了站点实测的空气温度、植被表面温度以及光合有效辐射通量密度（PPFD），并附带其过去24小时和240小时的平均值，此类数据用于运行MEGAN模拟以考量近期环境条件的影响。
