Multi-scale surface flux and meteorological elements observation dataset in the Hai River Basin (Guantao site-automatic weather station) (2008-2010)-National Tibetan Plateau Data Center

The data set contains observations from the automatic weather station as of 31 December 2010 as of 1 solstice January 2008.The site is located in hezhai village, guantao county, hebei province.The latitude and longitude of the observation point is 115.1274E, 36.5150N, and the altitude is 30m.

The acquisition frequency of the automatic weather station is 10s, and the output of 10min is once.The observation factors include air temperature and relative humidity (12.5m), and the direction is due north.Wind speed (12.7m), wind direction (12.7m), heading due north;Air pressure (installed in waterproof box);Rainfall (16m);Net radiation/four-component radiation (15.6m), facing due south;Infrared surface temperature (15.7m), the arm is facing south, the probe is facing vertically downward;The soil temperature and humidity probe was buried 2m south of the meteorological tower. The buried depth of the soil temperature probe was 0cm, 2cm, 5cm, 10cm, 20cm, 40cm, 60cm, 80cm and 100cm. The buried depth of the soil moisture sensor was 2cm, 5cm, 10cm, 10cm, 10cm, 10cm, 20cm, 60cm, 80cm and 100cm.Two soil hot plates (2) were buried 2cm underground, one under the vegetation and the other between the trees.Processing and quality control of observation data :(1) ensure 144 data per day (every 10min). If data is missing, it will be marked by -6999;(2) eliminate the moments with duplicate records;(3) data that is obviously beyond the physical meaning or the range of the instrument is deleted;(4) the format of date and time is unified, and the date and time are in the same column.For example, the time is: June 10, 2010 at 10:30.

Data released by the automatic weather station include:Date/Time, air temperature and humidity observation (ta_12.5m, rh_12.5m) (℃, %), wind speed (ws_12.7m) (m/s), wind direction (wd_12.7m) (°), pressure (Press) (hpa), precipitation (Rain) (mm), four-component radiation (DR, UR, DLR_Cor, ULR_Cor, Rn) (W/m2), surface radiation temperature (IRT_1, IRT_2) (℃),Soil heat flux (Gs_1, Gs_2) (W/m2), multi-layer soil moisture (Ms_2cm, Ms_5cm, Ms_10cm, Ms_20cm, Ms_40cm, Ms_60cm, Ms_100cm) (%) and multi-layer soil temperature (Ts_0cm, Ts_2cm, Ts_5cm, Ts_10cm, Ts_20cm, Ts_40cm, Ts_60cm, Ts_80cm, Ts_100cm) (℃).
