This data set includes all the observation data of automatic weather station of Maliantan grassland station in Dayekou from November 2, 2007 to December 31, 2009. 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 inclines slightly from southeast to northwest. The surface of Malian beach is alpine grassland, the main plant is Malian, the vegetation height is 0.2-0.5m. Main outcome measures: air pressure, precipitation, 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 station is a typical grass surface, and the observation items include: atmospheric wind temperature and humidity gradient observation (2m and 10m), air pressure, precipitation, radiation four components, 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 output data of the original collector is level 0; after preliminary sorting, there is no deletion, but the data with suspected problems is level 1; the data with 30 minute sampling period and quality control is level 2. The sorted data is stored month by month, and the naming rule is: site name + data level + AMS + data date. It is recommended that ordinary users use data above level 2.
Good data quality
