Multi-scale surface flux and meteorological elements observation dataset in the Haihe River Basin (Guantao site-large aperture scintillometer) (2008-2010)

The data set contains large aperture scintillator flux observation data from January 1, 2008, solstice, December 31, 2010.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 large aperture scintillation instrument is 1Hz, the effective height is 15.6m, the optical diameter length is 2760m, the longitude and latitude of the transmitting end is 115.1284E, 36.5274N, and the longitude and latitude of the receiving end is 115.1249E, 36.5028n.The data released by the large aperture scintillator is the average data of 30min after processing and quality control, in which the sensible heat flux is mainly obtained by combining with the data of automatic meteorological station and by iterative calculation based on the moning-obhoff similarity theory.(2) eliminate data with weak demodulation signal strength;(3) data of the time of precipitation and the hour before and after the precipitation are excluded;(4) data of weak turbulence under stable conditions were excluded (u* < 0.05m/s). Data released by the large aperture scintillator include: Date/Time Date/Time, air refractive index structure parameter Cn2 (m-2/3), sensible heat flux H_LAS (W/m2).

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

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) (℃). Please refer to Jia et al,(2012) for information of observation test or site, and Liu et al,(2013) for data processing.

Spatial layout of characteristic agriculture in Qinghai Tibet Plateau

The data includes the county-level data of characteristic agriculture distribution in the Qinghai Tibet Plateau, which lays the foundation for the spatial distribution and development of characteristic agriculture in the Qinghai Tibet Plateau. The data are from the development plan of Tibet Plateau characteristic agricultural products base (2015-2020), Qinghai province's 13th five year plan, Sichuan Province's 13th five year plan for agricultural and rural economic development, Xinjiang Uygur Autonomous Region's 13th five year plan for targeted poverty alleviation of agricultural characteristic industries (2016-2020), Yunnan Province's overall plan for plateau characteristic agricultural modernization( 2016-2020), implementation opinions on fostering and strengthening characteristic agricultural industries in Gansu Province to boost poverty alleviation, China National Geographic Indication product network (http://www.cgi.gov.cn/home/default/), regional layout planning of characteristic agricultural products (2013-2020). The data is the distribution of county-level characteristic agriculture, realizing the spatialization of county-level characteristic agriculture. The data can be applied to the research on the spatial distribution of characteristic agriculture and the development of characteristic agriculture in the future.
