The data set contains the eddy related flux data of Dayekou guantan forest station from December 27, 2007 to March 31, 2012. The station is located in Dayekou guantan in the south of Zhangye City, Gansu Province. The longitude and latitude of the observation point are 100 ° 15 ′ e, 38 ° 32 ′ n, and the altitude is 2835m. The observation site is located in the forest on the shady slope of guantan in dayekouzi watershed in the upper reaches of Heihe River. The forest is mainly spruce with a height of about 15-20m, the ground is covered with moss with a thickness of about 10cm, and the vegetation growth is good.\n
\nThe original observation items include: horizontal wind speed UX (M / s), horizontal wind speed uy (M / s), vertical wind speed UZ (M / s), ultrasonic temperature TS (Celsius), carbon dioxide concentration CO2 (mg / m ^ 3), water vapor concentration H2O (g / m ^ 3), air pressure press (kPa) and ultrasonic signal anomaly sign diag_ csat。 The instrument stand height is 20.02m, the ultrasonic orientation is 74 °, the distance between li-7500 and csat3 is 30cm, and the data sampling frequency is 10Hz per second.\n
\nLevel1 is the real-time output flux data of Campbell's own software, including sensible heat flux (HS), latent heat flux (le_wpl) and CO2 flux (fc_wpl); Level2 is the post-processing 30 minute flux data. The processing process includes field point elimination, coordinate rotation, frequency response correction, WPL correction and preliminary quality control. The processed data is stored month by month in. CSV format. The naming rule is: site name + data level + EC + data date. It is recommended that ordinary users use level2 data.
