MM2

Eddy covariance flux measurements has taken place at the site MM2 since 2007. The mast (3 m high) is located on a wet fen area called Rylekæret, about 1.5 km North of the Climate station (operated by ClimateBasis). Between 2007 and 2011 the system consisted of a LI6262 and Gill R2. Since 2012 a LI7200 and Gill HS are used. Data from LI6262+Gill R2 was logged at 20 Hz in Edisol software and fluxes calculated on halfhourly basis using EdiRe software, whereas data from LI7200+Gill HS is logged at 20 Hz on LI7550 and fluxes calculated on halfhourly basis using EddyPRO software.

自2007年起，MM2站点便持续开展涡动协方差通量（Eddy Covariance Flux）观测。该高3米的观测塔架坐落于一片名为Rylekæret的湿沼地带，距离由ClimateBasis运营的气候站以北约1.5公里处。2007年至2011年间，观测系统由LI6262分析仪与Gill R2超声风速仪组成。此阶段的观测数据通过Edisol软件以20赫兹的频率记录，并采用EdiRe软件以半小时为时间步长计算通量。自2012年起，观测系统更换为LI7200分析仪与Gill HS超声风速仪，其观测数据通过LI7550设备以20赫兹的频率记录，并通过EddyPRO软件以半小时为时间步长计算通量。
