TY - Data T1 - Heihe River Integrated Remote Sensing joint experiment: evapotranspiration data set of small lysimeter in super sample plot of Dayekou guantan forest station (2008) A1 - Bai Yunjie A1 - Chetao A1 - Tan Junlei DO - 10.12072/ncdc.NIEER.db1736.2022 PY - 2021 DA - 2021-09-14 PB - National Cryosphere Desert Data Center AB - This data comes from the super sample plot of guantan forest station in Dayekou basin. The tree vegetation of the super sample plot is pure Qinghai Spruce Forest, and the sample plot size is 100m × 100m。 The observation data for the sample plot mainly include: Ground Lidar scanning data, total station positioning measurement data, differential GPS positioning measurement data, tree survey data, leaf area index observation data, canopy spectrum measurement data, canopy camera observation data, soil evapotranspiration data, soil freezing tube observation data, surface roughness data, rainfall interception data Soil moisture measurement data, dry and wet weight measurement data of forest components, etc. This data mainly uses the self-made lysimeter to observe the characteristics of soil evapotranspiration in Qinghai Spruce Forest. It provides basic data for the development of watershed evapotranspiration model and ground verification data for remote sensing inversion of evapotranspiration. Observation time: 18:00 p.m. every day from June 1, 2008 to December 31, 2008. If there is rainfall on that day, it will be observed once after the rainfall is over. The weight difference before and after observation is used, and then the soil water evaporation is calculated in combination with the water density and lysimeter diameter (20cm). If there is transmitted rainfall in the rain collector under lysimeter, the transmitted rainfall shall be measured. Observation site: forest hydrological test plot of Dayekou guantan forest station. Observation contents: 1) for the control atmospheric rainfall, two rainfall tubes are observed at the same time and arranged on the flat river beach near the hydrological test sample site. 2) Through rainfall in the forest, a total of 20 rain cones are arranged in the sample plot, which is based on the canopy canopy canopy density above the rain cones. 3) Lysimeter weight at 18:00 every day. 4) The rainfall transmitted by the rain collector under l DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/e3dc119d-3273-43df-9136-b03ec5a69876 ER -
