AB  - This dataset contains flux observation data from large aperture scintillation meters at Sidaoqiao Station downstream of the Heihe Hydrological and Meteorological Observation Network. Two sets of large aperture scintillation meters are installed at the downstream Sidaoqiao station for observation. There is a large aperture scintillation instrument model BLS900 on the east side (point 1), with the north tower as the receiving end and the south tower as the transmitting end. The observation period of BLS900_1 was from March 13, 2014 to December 31, 2014. There is a large aperture scintillation instrument model BLS900 on the west side (point 2), with the north tower as the receiving end and the south tower as the transmitting end. The observation period of BLS900_2 was from January 1, 2014 to November 8, 2014. The site is located in Ejina Banner, Inner Mongolia, with underlying surfaces involving tamarisk, poplar, bare land, and cultivated land. The latitude and longitude of the North Tower at point 1 are 101.147E and 42.005N, while the latitude and longitude of the South Tower are 101.131E and 41.987N; The latitude and longitude of the north tower at point 2 are 101.137E, 42.008N, and the latitude and longitude of the south tower are 101.121E, 41.990N, with an altitude of approximately 873m. The effective height of the large aperture scintillation instrument is 25.5m, and the LAS optical path length at point 1 is 2390m, and the LAS optical path length at point 2 is 2380m, with a sampling frequency of 1min.
