This dataset contains meteorological element observation data from the Heihe Remote Sensing Station in the middle reaches of the Heihe Hydrological and Meteorological Observation Network from January 1, 2015 to December 31, 2015. The station is located on the east side of Dangzhai Town, Zhangye City, Gansu Province, with artificial grassland as the underlying surface. The latitude and longitude of the observation point are 100.4756E, 38.8270N, and the altitude is 1560m. The air temperature and humidity sensor is installed at 1.5 points, facing due north; The barometer is inside a waterproof box; The tipping bucket rain gauge is installed at a distance of 0.7 meters; The wind speed and direction sensor is installed at a distance of 10m, facing due north; The installation height of the four component radiometer is 1.5m, facing due south; Two infrared thermometers are installed at a height of 1.5m, facing due south, with the probes facing vertically downwards; The soil temperature probe is buried at a depth of 0cm on the surface and 2cm, 4cm, 10cm, 20cm, 40cm, 80cm, 120cm, and 160cm underground; Soil moisture probes are buried at 2cm, 4cm, 10cm, 20cm, 40cm, 80cm, 120cm, and 160cm locations; The average soil temperature probe is buried at 2cm and 4cm, and the soil heat flow plate (3 pieces) is buried at 6cm underground in sequence; Two photosynthetically active radiometers are respectively installed 1.5m above the canopy (with one probe vertically upwards and one downwards), facing due south. At the same time, there was observation of an evaporating dish (E601B, diameter 61.8cm).
