| Summary: | The Methane station (LGR) measures the methane and CO2 fluxes between soil and atmosphere in the fen during the field season (app. end of May until mid-October). The station was established in 2007 in the fen close to the InteractFen (Meteorology, Soil Properties, Snow Properties), EddyFen (Flux Monitoring) and SoilFen (Meteorology, Soil Properties) stations, where the soil is very wet and there is up to more than 1 m of peat. The system consists of six automatic chambers that open and close over a cycle of one hour. When a chamber closes an analyzer monitors the CO2 and CH4 concentration within the closed chamber. Comments: In 2014 chamber 3 and 4 were relocated to new spots and got new tubing. In 2016 the lids got renovated and chamber 1, 2, 5 and 6 got new tubing. 2019: Chambers 1, 2, 3 were exchanged with new chambers on same locations. 2020: Chambers 4, 5 and 6 were exchanged with new chambers on same locations. In 2019-2021 the station suffered from various problems causing gaps in data. The station ... |
