Dataset specification

  • Title: GeoBasis Disko - Meteorology - AWS2-Meteorology
  • Description: The automatic weather station AWS2 was installed in August 2012 in Østerlien just 100 meter east of Arctic Station. The station is located approximately 25 meter above sea level in a gentle south sloping area covered by low vegetation/dwarf shrubs. The time stamp refer to West Greenland Standard Time (UTC-3). The station consist of a 3 meter high mast with an east west pointing cross beam where sensors are mounted, and a 2 meter high mast where gasfluxes (CO2) are measured using eddy covariance technique. Soil parameters are measured in profiles and boreholes adjacent to the two masts. The AWS2-Meteorology file holds the following parameters (Shortwave radiation in and out, Longwave radiation in and out, Air temperature, Relative humidity, Wind speed, Wind direction, PAR, Air pressure and Albedo). Find gasflux data under FluxMonitoring (EC1-GasFlux). Find soil data from AWS2 under Soil (AWS2-GroundTemperatureP1 and P2, AWS2-SoilMoisture, AWS2-SoilTemperature, AWS2-SurfaceTemperature, AWS2-SoilHeatFlux). Find snow data from AWS2 under Snow (AWS2-SnowDepth, AWS2-SnowTemperature). All data are logged by 30-minute intervals. There is a gap in data from 10 September 2022 to 15 September 2022 due to service and maintenance of the station. Meteorology:Meteorology GeoBasis Disko: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:
