Dataset specification
- Title: GeoBasis Zackenberg - Meteorology - M7
- Description: M7 is one of six meteorological stations in the Zackenberg and Store Sødal Valley, where M7 is the only station in Store Sødal. Data from the station is found under meteorology (wind, temperature and relative humidity, short wave radiation) and snow properties (snow depth). The meteorological station M7 was installed in 2008. M7 is located in the western end of 'Store Sødal', about 500 West of the lake delta. Underneath the mast there are several bigger boulders, with a mix of salix and grasses between the boulders. Data is recorded on a CR1000 campbell scientific data logger. Data is recorded every half an hour. 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 relative humidity, May 3rd. 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:
