Multi-scale surface flux and meteorological elements observation dataset in the Hai River Basin (Daxing site-large aperture scintillometer) (2008-2010)

The dataset contains large aperture scintillator flux observation data from January 1, 2008, solstice, December 31, 2010.The station is located in weishanzhuang, daxing district, Beijing.The latitude and longitude of the observation point are 116.4271E, 39.6213N and 20m above sea level.

The acquisition frequency of the large aperture scintillation instrument is 1Hz, the effective height is 29.6m, the optical diameter length is 2480m, the longitude and latitude of the transmitting end is 116.4271E, 39.6213N, and the longitude and latitude of the receiving end is 116.4369E, 39.6422N.The data released by the large aperture scintillator is the average data of 30min after processing and quality control, in which the sensible heat flux is mainly obtained by combining with the data of automatic meteorological station and by iterative calculation based on the moning-obhoff similarity theory.(2) eliminate data with weak demodulation signal strength;(3) data of the time of precipitation and the hour before and after the precipitation are excluded;(4) data of weak turbulence under stable conditions were excluded (u* < 0.1m/s).

Data released by the large aperture scintillator include: Date/Time Date/Time, air refractive index structure parameter Cn2 (m-2/3), sensible heat flux H_LAS (W/m2)
