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，涡度协方差通量(eddy covariance flux)观测便在MM2站点持续开展。该高3米的观测塔坐落于名为Rylekæret的湿泥炭沼泽区域，地处由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与Gill R2组成；自2012年起，观测系统更换为LI7200与Gill HS。LI6262与Gill R2组合采集的原始数据以20赫兹采样率通过Edisol软件完成记录，并通过EdiRe软件以半小时为时间步长计算得到通量；而LI7200与Gill HS组合采集的数据则以20赫兹采样率经由LI7550完成记录，并通过EddyPRO软件以半小时为时间步长计算得到通量。
