This data set is the 2011 Alxa vorticity covariance data. Data is stored separately by collector: CR1000 includes soil moisture content, soil temperature and soil heat flux. The sampling frequency is 30min. The sampling time is May 25, 2011. See the table header for the meaning of each field Cr3000 includes the online processing results of csat3 and measured three-dimensional ultrasonic wind speed and H2O and CO2 flux data, in addition, it includes four radiation, albedo, air temperature and humidity, water vapor pressure and atmospheric pressure, sampling frequency is 30min, acquisition time: May 24, 2011, the meaning of each field is shown in the header
