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站采用涡度相关法（eddy covariance method），对海拔40米的沼泽湿地样地开展二氧化碳通量观测，该站点毗邻甲烷通量监测站（Methane (Flux Monitoring)）、InteractFen站（开展气象、土壤特性、积雪特性观测）以及SoilFen站（开展气象、土壤特性观测）。为刻画季节碳平衡的年际变化特征，研究团队通过涡度相关法测定了二氧化碳（CO₂）的生态系统净交换量（net ecosystem exchange, NEE）。受电力供应限制，该站点仅在夏季野外观测季（约5月至10月）开展数据采集。该站点始建于2007年，2018年完成了数米距离的迁址及观测仪器的更新升级。2018年及之后的数据存储路径为"EddyFen_2018-"（2007-2018年采用LiCor 7000型分析仪，2018年起更换为LiCor 7200型分析仪；2007年起统一使用Gill 1210R3型超声风速仪）。
