This dataset contains flux observation data from large aperture scintillation meters at the Daman Station in the middle reaches of the Heihe Hydrological and Meteorological Observation Network. Large aperture scintillation meters of BLS450 and BLS900 models have been installed at the midstream Daman Station. The north tower serves as the receiving end and transmitting end of BLS900, while the south tower serves as the transmitting end and receiving end of BLS900 and BLS450. The observation period is from January 1, 2017 to December 31, 2017. The site is located in the Daman Irrigation District of Zhangye City, Gansu Province, with corn, orchards, and greenhouses as the main base. The latitude and longitude of the North Tower are 100.3785E, 38.8607N, and the latitude and longitude of the South Tower are 100.3685E, 38.8468N, with an altitude of about 1556m. The effective height of the large aperture scintillation meter is 22.45m, the optical path length is 1854m, and the sampling frequency is 1min.
