InteractFen (I5Nf) is one of two automatic energy balance stations in Kobbefjord that was setup in 2011. Data from the station is found under Meteorology (air temperature, relative humidity, radiation, wind, air pressure), Soil Properties (water fraction, ground water level, soil temperatures) and Snow Properties (snow temperatures, snow depht). The station is placed in the fen (40 m.a.s.l.) close to the SoilFen (Meteorology, Soil Properties), EddyFen and Methane stations (Flux Monitoring). The SnowProperties dataset from the station consists of snow depth (Campbell, SR50A) and snow temperatures (thermocouples, 107T). All data is logged every 30 minutes (West Greenlandic Winter Time, CR1000). Data comments: The station has suffered from power problems from 2015-2018 causing data gaps in autumn/winter. In June 2018 air temperature, relative humidity and wind sensors were added to the station setup. Snow depth: Snow free periods set to 0 since 2015. Since 2018, SR50A showed many false v Snow Properties:Snow Properties GeoBasis Nuuk:The GeoBasis monitoring programme focuses on selected abiotic characteristics in order to describe the state of Greenlandic terrestrial environments and their potential feedback effects in a changing climate. Monitored plot data is up-scaled to a landscape level and is used to improve ecosystem models to be able to quantify these feedback mechanisms. The GeoBasis programme provides an active response to recommendations in international assessments such as ACIA and SWIPA; and is continuously being adapted based on AMAP and other international founded recommendations. Furthermore, the GeoBasis programme is directly involved in several international networks and research projects (e.g. the Circumpolar Active Layer Monitoring (CALM) programme, the Nordic Centre of Excellence DEFROST, the Danish Centre of Excellence CENPERM, the EU-projects PAGE21 and INTERACT, and the Arctic Research Centre at Aarhus University). The GeoBasis programme is divided into a number of sub-groups, including:
