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测点便持续开展微气象监测（Micrometeorological monitoring）。2011年，在现有涡度协方差铁塔（eddy covariance mast）东侧约5米处架设了能量平衡观测铁塔。该铁塔坐落于排水良好的岩须灌丛（Cassiope heath）中，距由ClimateBasis运营的“气象站”北侧约150米。观测数据每半小时采集一次。 2015年9月，为优化本测点的积雪温度监测性能，紧邻能量平衡铁塔加装了一支全新测温杆，其搭载16支BetaTherm热敏电阻（BetaTherm thermistors），可实现每10厘米一层的温度测量。2016年8月，本测点开展了归一化差分植被指数（Normalized Difference Vegetation Index, NDVI）观测。
