Carbon dioxide fluxes and carbon balance of an agricultural grassland in southern Finland

The data set contains CO₂ and H₂O eddy covariance flux data and meteorological measurements from agricultural grassland site at Qvidja in southern Finland (60.29550°N, 22.39281°E, elevation 5 m) measured in 2018 - 2020. Additionally, the data set contains leaf area index data and measurements of soil organic carbon content. Fluxes_Heimsch_et_al_2020.csv contains the CO₂ and H₂O flux data. Meteorology_Heimsch_et_al_2020.csv and Precipitation_Heimsch_et_al_2020.csv contain the meteorological measurements. LAI_Heimsch_et_al_2020.csv contains the leaf area index data obtained from the Sentinel-2 satellite. SOC_Heimsch_et_al_2020.xlsx contains the measurements of soil organic carbon from five soil core samples.本数据集收录了芬兰南部奎维贾（Qvidja）农业草地站点在2018年至2020年间获取的二氧化碳（CO₂）与水汽（H₂O）涡度协方差通量（eddy covariance flux）数据及气象观测数据；该站点地理坐标为60.29550°N，22.39281°E，海拔5米。此外，本数据集还包含叶面积指数（Leaf Area Index）数据与土壤有机碳含量测定数据。各数据文件对应内容如下：Fluxes_Heimsch_et_al_2020.csv存储二氧化碳与水汽通量数据；Meteorology_Heimsch_et_al_2020.csv与Precipitation_Heimsch_et_al_2020.csv收录气象观测数据；LAI_Heimsch_et_al_2020.csv包含通过哨兵-2卫星（Sentinel-2）获取的叶面积指数数据；SOC_Heimsch_et_al_2020.xlsx则包含5个土壤岩心样本的土壤有机碳测定结果。
