该数据集包含了2008年1月1日至2010年12月31日的大孔径闪烁仪通量观测数据。站点位于河北省馆陶县河寨村，下垫面是玉米/小麦，棉花。观测点的经纬度是115.1274E, 36.5150N，海拔30m
\n\n主要的质量控制步骤包括：（1）剔除Cn2达到饱和的数据；（2）剔除解调信号强度较弱的数据；（3）剔除降水时刻及其前后一小时的数据；（4）剔除稳定条件下的弱湍流的数据（u*小于0.05m/s）。
\n\n大孔径闪烁仪发布的数据包括：日期/时间Date/Time，空气折射指数结构参数Cn2 （m-2/3），感热通量H_LAS （W/m2）。
\n\n观测试验或站点信息请参考 Jia et al,(2012),数据处理请参考Liu et al.(2013)。
