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米的湿泥炭沼泽观测站点开展二氧化碳通量监测，该站点毗邻甲烷通量监测站（Methane (Flux Monitoring)）、InteractFen站（负责气象、土壤特性、积雪特性监测）以及SoilFen站（负责气象、土壤特性监测）。为刻画季节碳平衡的年际变化特征，研究人员通过涡度协方差法测量了生态系统二氧化碳（CO₂）净交换量（net ecosystem exchange, NEE）。由于电力供应不足，仅在夏季野外观测季（约5月至10月）采集数据。该站点于2007年建成投用，2018年被迁移了数米，同时更换了观测仪器。2017年之后的数据可在"EddyFen_2018-"目录下获取（2007-2018年使用的仪器为LiCor 7000，2018年至今使用LiCor 7200，2007年至今使用Gill 1210R3）
