Dataset specification

• Title: GeoBasis Disko - Soil - AWS2-SoilHeatFlux
• Description: The automatic weather station AWS2 was installed in August 2012 in Østerlien just 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 station is running West Greenland Standard Time (UTC-3). The station consist of a 3 meter high mast with an east west pointing cross beam where snow depth, radiation, temperature, relative humidity, wind (speed and direction) are measured, and a 2 meter high mast where gasfluxes (CO2) are measured using eddy covariance technique. Soil heat fluxes are measured in the upper soil (sensors are installed 5 cm below the ground surface. Find more data from AWS2 under Soil (AWS2-GroundTemperatureProfile1 and Profile2, AWS2-Moisture, AWS2-SurfaceTemperature). Find meteorological data from AWS2 under Meteorology (AWS2-Meteorology). Find snow depth and snow temperature under Snow (AWS2-SnowDepth, AWS2-SnowTemperature). All data are logged by 30 minutes interval using a CR1000 datalogger from Campbell Scientific. Soil water chemistry down to 50 cm´s depth is measured in samples collected from a nearby soil profile SW1. Find these data under Soil (SW1-SoilWaterChemistry). Find gasflux measurements from the eddy covariance mast under FluxMonitoring (EC1-GasFlux). Soil:Soil 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:
