Installation of meteorological observation and gradient observation stations at the Inner Mongolia Grassland Station of the Chinese Academy of Sciences
The meteorological element observation field of Inner Mongolia Grassland Station is an observation field with an area of ​​25 m × 25 m built near the site. Since January 1, 1982, formal observations have been started according to the requirements of county-level meteorological stations. Meteorological factors for artificial observation include temperature, atmospheric relative humidity, air pressure, precipitation, evaporation, ground temperature, soil temperature (5, 10, 15, 20, 40 cm) sunshine (hours), percentage of sunshine, wind speed, wind direction, etc. Automatic weather station observation indicators include: automatic monitoring of temperature, atmospheric humidity, air pressure, radiation, precipitation, ground temperature, wind direction, wind speed and other factors
In addition, in the Leymus chinensis, a microclimate gradiometer is installed. The monitored items include: atmospheric temperature, humidity, radiation, ground temperature, temperature of seven soil layers, wind speed and wind direction of four gradients.
