A dataset of carbon-water vapor fluxes and meteorological observations in the upper reaches of Heihe river basin from 2013 to 2022
The upper reaches of the Heihe River are known as the"water tower"of the Heihe River Basin.Understanding the temporal variations and influencing factors of carbon and water fluxes and meteorological elements in this area is crucial for maintaining the ecological balance of the oases in the middle and lower reaches,as well as for water resource management.This study focuses on the alpine region of the upper Heihe River Basin and systematically compiles carbon and water fluxes and meteorological data collected from 2013 to 2022 at nine observation sites established in this region.These sites include four eddy covariance systems,nine automatic weather stations,and one scintillometer.The observation projects encompass ecosystem net carbon exchange,evapotranspiration(latent heat flux),sensible heat flux,air temperature,relative humidity,wind speed,wind direction,downward/upward shortwave radiation,downward/upward longwave radiation,net radiation,atmospheric pressure,precipitation,infrared radiation temperature,photosynthetically active radiation,soil temperature and soil moisture profile,soil heat flux,and average soil temperature.This dataset has undergone rigorous processing and quality control and can be used for research on ecological hydrological processes,characteristics of carbon and water flux changes,and coupling mechanisms in alpine regions.Additionally,it provides essential driving and validation data for ecological hydrological process modeling and other related studies.
