Dataset specification

  • Title: GeoBasis Zackenberg - Flux monitoring - MM2
  • Description: Eddy covariance flux measurements has taken place at the site MM2 since 2007. The mast (3 m high) is located on a wet fen area called Rylekæret, about 1.5 km North of the Climate station (operated by ClimateBasis). Between 2007 and 2011 the system consisted of a LI6262 and Gill R2. Since 2012 a LI7200 and Gill HS are used. Data from LI6262+Gill R2 was logged at 20 Hz in Edisol software and fluxes calculated on halfhourly basis using EdiRe software, whereas data from LI7200+Gill HS is logged at 20 Hz on LI7550 and fluxes calculated on halfhourly basis using EddyPRO software. Flux monitoring:Flux monitoring GeoBasis Zackenberg: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:
