Dataset specification

  • Title: GeoBasis Zackenberg - Meteorology - M3
  • Description: M3 is one of six meteorological stations in the Zackenberg and Store Sødal Valley. Data from the station is found under meteorology (wind, temperature and relative humidity, short wave and long wave radiation, as well as NDVI), soil properties (soil moisture and soil heat flux) and snow properties (snow depth). M3 is located on a gently south-west facing slope, half way up the mountain Aucella, in an elevation of 420 meters. The station was installed in 2003 and data recorded every half hour, except snow depth and soil moisture which was recorded every 6th hour until august 2012. The vegetation underneath the mast is dominated by Salix Arctica. Data was iniatially recorded using a CR10x Campbell scientific data logger, but this was changed to a CR1000 data logger in August 2012. 2017: Wind vanes A100R (measuring wind speed and gust) and W200P (wind direction and standard deviation) were exchanged with Young Alpine wind monitor (05103-45 Wind monitor), as well as temperature and relati Meteorology:Meteorology 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:
