Dataset specification

  • Title: GeoBasis Disko - Meteorology - AWS1-Meteorology
  • Description: The automatic weather station AWS1 was installed in October 1990 and removed in 2018. We included the main parameters from this station in the GEM database as most parameters are continued at the GeoBasis station AWS2. AWS1 was running West Greenland Standard Time (UTC-3). The automatic weather station was installed at the scientific leader´s house approximately 25 meter above sea level and 300 m from the coast. Wind (speed and direction) and Air temperature were measured at a 9.5 meter high mast. Liquid precipitation were measured at a 2 meter high separate mast. All parameters were logged by 30 minutes interval. Data were monitored and stored by AANDERAA instruments and datalogger. Find more information about the AWS1 station on: Due to a datalogger failure, average wind speed data became available first after 26 May 1994. The wind speed measurements end 31 December 2012. The relative humidity measurements end 16 November 2012. The station had a breakdown in July 2002 and remained unstable until October 2004. During that period, the main parameters were gap-filled with data from a nearby station operated by Asiaq (Greenland survey). Find ground temperatures measured at AWS1 under Soil (AWS1-GroundTemperature). Find data from AWS2 under Meteorolgy, Soil, and Snow (see AWS2-Meteorology, AWS2-SoilTemperature, AWS2-SnowDepth, AWS2-SoilMoisture). 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:
