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. Contact GeoBasis Zackenberg manager in case of interest.

M2是扎科内尔（Zackenberg）与Store Sødal谷内的六座气象站之一。该站点的观测数据涵盖气象要素（风速、气温、相对湿度、短波与长波辐射，以及归一化差分植被指数（NDVI））、土壤属性（土壤湿度与土壤热通量）及积雪属性（积雪深度）。
M2站点坐落于ZEROCALM-2网格内部的南向坡地，该网格开展冻土活动层监测工作。塔架下方的植被以北极柳（salix arctica）为优势物种。
该站点的观测工作始于2003年8月5日。
M2站点的常规数据采集频率为每半小时一次，但积雪深度与土壤湿度除外：2012年8月前，这两类参数的采集频率为每6小时一次。
2003年至2012年间，观测数据由CR10X型坎贝尔科学（Campbell Scientific）数据记录仪采集；2012年8月，设备更换为CR1000型数据记录仪。
由于该站点地处南向坡地（扎科内尔地区冬季的主导背风坡），多个冬季均出现积雪覆盖站点的情况，导致供电不足并产生数据缺失。
该站点同时开展土壤温度测量，但由于数据记录仪的温度传输故障，相关数据未纳入本数据库。如有相关需求，请联系GeoBasis Zackenberg管理员。
