EddyFen

The EddyFen station measures carbon dioxide fluxes via eddy covariance method in the wet fen site (40 m.a.s.l) close to the Methane (Flux Monitoring), InteractFen (Meteorology, Soil Properties, Snow Properties) and SoilFen (Meteorology, Soil Properties) stations. In order to describe the inter-annual variability of the seasonal carbon balance, net ecosystem exchange (NEE) of carbon dioxide (CO2) is measured by applying the eddy covariance method. Due to lack of power, data is only collected in the summer field season (app. May-October). The station was established in 2007. In 2018 the station was moved a couple of meters and the instrumentation was changed. Data after 2017 is found under \"EddyFen_2018-\" (2007-2018: LiCor: 7000, 2018-: LiCor 7200, 2007-: Gill 1210R3)

EddyFen站采用涡度协方差法（eddy covariance method），在海拔40 m.a.s.l.的湿泥炭沼泽样地测定二氧化碳通量，该站点毗邻甲烷（通量监测）站、InteractFen（气象、土壤特性、积雪特性）站与SoilFen（气象、土壤特性）站。为刻画季节碳平衡的年际变化特征，研究团队采用涡度协方差法测定二氧化碳（CO₂）的生态系统净交换量（net ecosystem exchange, NEE）。由于电力供应不足，该站仅在夏季野外考察期（约5月至10月）采集数据。该站始建于2007年，2018年搬迁数米并更换了观测仪器。2017年之后的数据可在"EddyFen_2018-"目录下获取（2007-2018年使用LiCor 7000型仪器，2018年至今使用LiCor 7200型仪器，2007年至今使用Gill 1210R3型仪器）
