SMEAR I Värriö forest eddy covariance

This dataset contains time series of turbulent exchange of CO2, heat and momentum measured at two heights at SMEAR I research station in Värriö, Salla, Finland, during years 2012–2021. The flux measurements were done in tower above the forest and at 2.5 m height below the canopy. The data were exported from SMEAR database on the dataset release date. Most recent version of the data are available at https://smear.avaa.csc.fi/.本数据集涵盖2012年至2021年间，于芬兰萨拉市瓦里奥地区的SMEAR I研究站两处高度处采集的二氧化碳（CO₂）、热量与动量湍流交换时序数据。此次湍流通量观测分别在林上铁塔及林冠下方2.5米高度处开展。本数据集于发布当日从SMEAR数据库（SMEAR）导出，数据的最新版本可通过https://smear.avaa.csc.fi/获取。
