AB  - The data set includes the observation data of 10 m tower eddy correlator from January 1, 2014 to December 31, 2014. The site is located in donghuayuan Town, Huailai County, Hebei Province. The longitude and latitude of the observation point are 115.7880e, 40.3491n and 480m above sea level. The acquisition frequency of the eddy correlator is 10Hz, the frame height is 5m, the ultrasonic direction is north, and the distance between the ultrasonic anemometer (gill & csat3 (replaced on October 9, 2014)) and the CO2 / H2O analyzer (li7500a) is 18cm (15cm after October 9). The observation data released by the eddy correlator include: date / time, wind direction WDIR (?), horizontal wind speed wnd (M / s), standard deviation of lateral wind speed STD uuy (M / s), ultrasonic virtual temperature TV (k), water vapor density H2O (g / m3), carbon dioxide concentration CO2 (mg / m3), friction velocity ustar (M / s), obkhov length, sensible heat flux HS (w / m2), latent heat flux Le (w / m2) , carbon dioxide flux FC (mg / (M2S)), quality mark of sensible heat flux qa_hs, quality mark of latent heat flux qa_le. The quality identification of sensible heat, latent heat and carbon dioxide flux is divided into three levels (quality identification 0: (Δ st & lt; 30, ITC & lt; 30); 1: (Δ st & lt; 100, ITC & lt; 100); the rest is 2). The meaning of data time, for example, 0:30 represents the average of 0:00-0:30; data is stored in *. XLS format. Please refer to Yang Guangchao et al. (2015) for observation test or site introduction and Liu et al. (2013) for data processing.
