M2

M2 is one of six meteorological stations in the Zackenberg and Store Sødal Valley. Data from the station is found under meteorology (wind, temperature and relative humidity, short wave and long wave radiation, as well as NDVI), soil properties (soil moisture and soil heat flux) and snow properties (snow depth). M2 is located on a south facing slope in side the ZEROCALM-2 grid, in which active layer is monitored. The vegetation underneath the mast is dominated by salix arctica. Measurements at this station were initiated on the 5th of August 2003. At M2 data is recorded every half hour, except for snow depth and soil moisture which was recorded every 6th hour before August 2012. Between 2003-2012 data was recorded using a CR10x campbell scientific data logger. In August 2012 this was changed to a CR1000 data logger. As the station is situated on a southfacing slope (dominating leeward side during winter in Zackenberg), the station has been covered in snow during several winters, resulting in low power and missing data. Soil temperature is also measured at the station, but data not published in the database, due to problems with propagating datalogger temperature.
