The data set contains the observation data of all automatic weather stations of Dayekou Maliantan grassland station from November 2, 2007 to December 31, 2009. The site is located in Malian beach, Dayekou, in the south of Zhangye City, Gansu Province. The longitude and latitude of the observation point are 100 ° 18 ′ e, 38 ° 33 ′ n, and the altitude is 2817m. The test site is located in dayekouzi watershed in the upper reaches of Heihe River. The terrain around the test site is relatively flat and open, and the terrain drops slightly from southeast to northwest. The surface of Malian beach is alpine grassland, the main growing plant is Malian, and the vegetation height is 0.2-0.5m.
The site is a typical grass ground surface. The observation items include: atmospheric wind temperature and humidity gradient observation (2m and 10m), four components of air pressure, precipitation and radiation, multi-layer soil temperature (5cm, 10cm, 20cm, 40cm, 80cm and 120cm), soil moisture (5cm, 10cm, 20cm, 40cm, 80cm and 120cm) and soil heat flux (5cm and 15cm).
The original collector output data is level 0; After preliminary sorting, there is no deletion, but the data marked with suspected problems is level 1; Those uniformly sorted into 30 minute sampling period and subject to quality control are classified as level 2. The sorted data will be stored month by month. The naming rule is: site name + data level + AMS + data date. It is recommended that ordinary users use data above level 2. For details, please refer to the "guide for using meteorological and hydrological flux data" in "other online resources" below
