EddyFen_2018-

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 before is found under \"EddyFen\". (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米（m.a.s.l.）的沼泽湿地站点开展二氧化碳通量观测，该站点毗邻甲烷（通量监测）站、InteractFen站（气象、土壤特性、积雪特性）与SoilFen站（气象、土壤特性）。为刻画季节碳平衡的年际变化特征，研究团队通过涡度协方差法测定二氧化碳（CO₂）的净生态系统交换（net ecosystem exchange, NEE）。受电力供应限制，仅在夏季野外观测季（约5月至10月）采集数据。该站点始建于2007年，2018年时移位约数米且观测仪器完成更新。2018年之前的数据集可在"EddyFen"分类下获取，仪器配置信息为：2007—2018年：LiCor 7000；2018年至今：LiCor 7200；2007年至今：Gill 1210R3。
