MM1_Snow_depth

Micrometeorological monitoring has taken place at the site MM1 since 2000. In 2011 an energy balance mast was put up about five meters East of the existing eddy covariance mast. The mast is located on a well drained Cassiope heath, about 150 meters North of the 'Climate station' (operated by ClimateBasis). Data is recorded every half hour. In September 2015 a new temperatur rod with 16 BetaTherm thermistors (measuring temperature for every 10 cm) was installed adjacent to the energy balance mast, in order to improve the snow temperature measurements, at the site. In August 2016, NDVI is measured at the site.自2000年起，MM1站点便持续开展微气象监测（micrometeorological monitoring）工作。2011年，研究人员在现有涡度协方差（eddy covariance）通量塔东侧约5米处架设了能量平衡塔（energy balance mast）。该塔坐落于排水良好的岩须灌丛（Cassiope heath）地带，距由ClimateBasis运营的"气候站"北侧约150米，监测数据以每半小时为间隔进行采集存储。 2015年9月，为优化本站点的积雪温度监测精度，研究人员在能量平衡塔附近加装了一套搭载16个BetaTherm热敏电阻（每10厘米布设一个测温点位）的新型温度探针。2016年8月，研究人员在该站点开展了归一化差分植被指数（Normalized Difference Vegetation Index，NDVI）的野外测量工作。
