GeoBasis Nuuk - Meteorology - M500

The microclimate station, M500, was established in 2007 and is located on bare rock 500 m.a.s.l at the mountain SE of the fen close to the automatic cameras K2 and K3 (Automatic Photomonitoring). The data is logged (CR1000 logger) every five minutes (and includes air temperature and relative humidity (2007-2018: Vaisala, HMP45, 2018-: Campbell, CS215) measured in radiation shield 2 m above ground, short wave incoming solar radiation (KippZonen, SP Lite) and radiometric measured surface temperature (Apogee, IRR-P). Data comments: In 2018 the HMP45 air temperature and relative humidity sensor was changed with a CS215 sensor causing a shift in the relative humidity data. Meteorology:Meteorology GeoBasis Nuuk: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:
