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是扎科贝永（Zackenberg）与斯托勒瑟达尔谷（Store Sødal Valley）所辖六座气象站之一。该站的观测数据涵盖气象类指标（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））、土壤特性类指标（土壤含水量与土壤热通量）及积雪特性类指标（积雪深度）。
M2站坐落于ZEROCALM-2网格内的南向坡地，该网格同步开展活动层监测工作。铁塔下方的原生植被以北极柳（Salix arctica）为优势种。
该站的观测工作于2003年8月5日正式启动。
该站常规观测数据的采集频率为每半小时一次；2012年8月之前，积雪深度与土壤含水量的观测频率为每6小时一次。
2003年至2012年期间，观测数据由坎贝尔科学（Campbell Scientific）公司的CR10X数据采集器记录；2012年8月起，采集设备更换为CR1000数据采集器。
由于该站位于南向坡地（扎科贝永地区冬季的主导背风侧），多个冬季期间该站会被积雪覆盖，导致供电不足并出现数据缺失情况。
该站同时开展土壤温度测量，但因数据采集器的温度传输故障，相关数据未纳入本数据库。如有相关需求，请联系扎科贝永地理基础数据管理员（GeoBasis Zackenberg manager）。
