该数据集包含了2012年10月14日至2013年12月31日的黑河水文气象观测网上游阿柔超级站的大孔径闪烁仪观测数据。上游阿柔超级站分别架设了两台型号为BLS450_AR和zzlas的大孔径闪烁仪，北塔为zzlas的接收端和BLS450_AR的发射端，南塔为zzlas的发射端和BLS450_AR的接收端。其中zzlas自2012年10月14日开始观测，BLS450_AR的观测时间为2013年8月9日至2013年12月10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100.4712E，38.0568N，南塔的经纬度是100.4572E，38.0384N，海拔高度约3033m。大孔径闪烁仪的有效高度9.5m，光径路线长度是2390m，BLS450和zzlas的采样频率分别为5Hz和1Hz，平均为1min输出。

From November 10 to November 23, 2012 and from March 14 to April 10, 2013, the data were eliminated due to the drift of the zzlas signal; There was no data from April 10 to May 31, 2013 due to the inclination of Las tower
