The data set includes the observation data of 10m tower automatic weather station from January 13, 2014 to December 31, 2014. The site is located in donghuayuan Town, Huailai County, Hebei Province. The underlying surface is watered corn. The longitude and latitude of the observation point are 115.7880e, 40.3491n and 480m above sea level.
The data released by the automatic weather station include: date / time, air temperature and humidity observation (ta_5m, Rh_5m (℃,%), wind speed (ws_10m) (M / s), wind direction (WD) (℃), pressure (HPA), precipitation (rain) (mm), four component radiation (DR, ur, DLR, ULR, RN) (w / m2), surface radiation temperature (irt_1, irt_) (℃), soil heat flux (gs_1, gs_, gs_) (w / m2) Multi layer soil moisture (MS ﹤ 2cm, MS ﹤ 4cm, MS ﹐ 10cm, MS ﹐ 20cm, MS ﹐ 40cm, MS ﹐ 80cm, MS ﹐ 120cm, MS ﹐ 160cm) (℃), average soil temperature (TS ﹐ 2cm, TS cm, TS ﹐ 20cm, TS cm, TS ﹐ 160cm) (℃), average soil temperature (tcav (℃).

The automatic weather station is installed on a 10m tower, with the acquisition frequency of 30s and output once in 10min. The observation elements include air temperature and relative humidity (5 m), which are oriented to the north; wind speed (10 m), wind direction (10 m), which is oriented to the north; air pressure (installed in the waterproof box); rainfall (10 m); four component radiation (5 m), which is oriented to the South; infrared surface temperature (5 m), which is oriented to the South and the probe is oriented to the vertical down
The soil temperature and humidity probe is buried at 1.5m in the south of the meteorological tower, 2cm, 4cm, 10cm, 20cm, 40cm, 80cm, 120cm and 160cm in depth, 2cm, 4cm, 10cm, 20cm, 40cm, 80cm, 120cm and 160cm in depth; the average soil temperature is buried at 2, 4cm underground; the soil heat flow plate (3 pieces) is buried at 6cm underground.
Processing and quality control of observation data: (1) 1440 data (every 10min) shall be ensured every day, and if there is any missing data, it shall be marked by - 6999; (2) the time with duplicate records shall be eliminated; (3) the data that obviously exceeds the physical meaning or the measuring range of the instrument shall be deleted; (4) the format of date and time shall be unified, and the date and time shall be in the same column. For example, the time is 10:30, June 10, 2014. From January 13 to March 26, the data of soil moisture at 20cm depth was wrong due to probe problems; from January 21 to March 26, the data of soil moisture at 120cm depth was wrong due to probe problems; from March 17 to March 26, the data of soil moisture at 2,4,10,20cm depth was wrong due to probe problems. Soil heat flux G2 had problems from June 16 to July 9 due to the problem of heat flow plate.
