黑河生态水文遥感试验：上游阿柔超级站大孔径闪烁仪水文气象观测网数据集（2012-2013）

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。This dataset contains large aperture scintillometer (LAS) observation data from the Arou Super Station, the upstream site of the Heihe Hydrological and Meteorological Observation Network, covering the period from October 14, 2012 to December 31, 2013. Two large aperture scintillometers with model numbers BLS450_AR and zzlas were installed at this upstream super station. The north tower serves as the receiving end for zzlas and the transmitting end for BLS450_AR, while the south tower acts as the transmitting end for zzlas and the receiving end for BLS450_AR. Specifically, zzlas commenced observations on October 14, 2012, whereas BLS450_AR operated from August 9, 2013 to December 10, 2013. The station is located in Caodaban Village, Arou Township, Qilian County, Qinghai Province, with an underlying surface of alpine grassland. The geographic coordinates of the north tower are 100.4712°E, 38.0568°N, and those of the south tower are 100.4572°E, 38.0384°N. The elevation of both towers is approximately 3033 m. The effective mounting height of the LAS instruments is 9.5 m, with an optical path length of 2390 m. The sampling frequencies of BLS450_AR and zzlas are 5 Hz and 1 Hz, respectively, with 1-minute averaged outputs provided.
