该数据集包含了黑河流域地表过程综合观测网上游阿柔站的大孔径闪烁仪通量观测数据。上游阿柔站分别架设了BLS450和zzlas型号的大孔径闪烁仪，北塔为zzlas的接收端和BLS450的发射端，南塔为zzlas的发射端和BLS450的接收端。观测时间为2018年1月1日至2018年12月31日。站点位于青海省祁连县阿柔乡草达坂村，下垫面是高寒草地。北塔的经纬度是100.4712°E，38.0568N，南塔的经纬度是100.4572°E，38.0384°N，海拔高度约3033m。大孔径闪烁仪的有效高度9.5m，光径长度是2390m，采样频率是1min。\n
大孔径闪烁仪原始观测数据为1min，发布的数据为经过处理与质量控制后的数据，其中感热通量主要是结合自动气象站观测数据，基于莫宁-奥布霍夫相似理论通过迭代计算得到，主要的质量控制步骤包括：（1）剔除Cn2达到饱和的数据（BLS450：Cn2>7.25E-14，zzlas：Cn2>7.84 E-14）；（2）剔除解调信号强度较弱的数据（BLS450：Mininum X Intensity <50；zzlas：Demod>-20mv）；（3）剔除降水时刻的数据；（4）剔除稳定条件下的弱湍流的数据（u*小于0.1m/s）。在迭代计算过程中，对于BLS450，选取Thiermann and Grassl(1992)的稳定度普适函数；对于zzlas，选取Andreas, 1988的稳定度普适函数，详细介绍请参考Liu et al. (2011, 2013)。由于仪器故障，2018年7月5日-8月24日大孔径闪烁仪数据缺失。\n
关于发布数据的几点说明：（1）上游LAS数据以BLS450为主，缺失时刻由zzlas观测补充，两者都缺失则以-6999标记。（2）数据表头：Date/Time ：日期/时间（格式：yyyy/m/d h:mm），Cn2 ：空气折射指数结构参数（单位：m-2/3），H_LAS ：感热通量（单位：W/m2）。数据时间的含义，如0:30代表0:00-0:30的平均；数据以*.xlsx格式存储。\n

This dataset contains flux observation data from the large aperture scintillation instrument at the Aruo Station on the comprehensive observation network of surface processes in the Heihe River Basin. The upstream Aruo station has installed large aperture scintillation meters of BLS450 and Zolas models respectively. The north tower serves as the receiving end of Zolas and the transmitting end of BLS450, while the south tower serves as the transmitting end of Zolas and the receiving end of BLS450. The observation period is from January 1, 2018 to December 31, 2018. The station is located in Caodaban Village, Aruo Township, Qilian County, Qinghai Province, with a high-altitude grassland as the underlying surface. The latitude and longitude of the North Tower are 100.4712 ° E, 38.0568N, and the latitude and longitude of the South Tower are 100.4572 ° E, 38.0384 ° N, with an altitude of approximately 3033m.
