A major research plan entitled “Integrated on the ecohydrological process of Heihe River Basin” was launched by National Natural Science Foundation China in 2010. One key aims this is to establish a platform that integrates observation, data management, and model simulation foster twenty-first-century watershed science China. Based diverse needs interdisciplinary studies within plan, program called Watershed Allied Telemetry Experimental Research (HiWATER) implemented. The overall objective...
Abstract. We analyzed the seasonal variations of energy balance components over three different surfaces: irrigated cropland (Yingke, YK), alpine meadow (A'rou, AR), and spruce forest (Guantan, GT). The were measured using eddy covariance (EC) systems a large aperture scintillometer (LAS) in Heihe River Basin, China, 2008 2009. also determined source areas EC LAS measurements with footprint model for each site discussed differences between sensible heat fluxes at AR. results show that main...
Core Ideas Heihe was the first basin-scale integrated observatory network established in China. An intensive flux observation matrix experiment conducted. New techniques, e.g., wireless sensor network, matrix, and airborne remote sensing, are used. The is useful land surface processes research. Research on at catchment scale has drawn much attention over past few decades, a number of watershed observatories have been worldwide. River Basin (HRB), which contains second largest inland river...
The Watershed Allied Telemetry Experimental Research (WATER) is a simultaneous airborne, satellite‐borne, and ground‐based remote sensing experiment aiming to improve the observability, understanding, predictability of hydrological related ecological processes at catchment scale. WATER consists cold region, forest, arid region experiments as well hydrometeorology took place in Heihe River Basin, typical inland river basin northwest China. field campaigns have been completed, with an...
In view of future changes in climate, it is important to better understand how different plant functional groups (PFGs) respond warmer and drier conditions, particularly temperate regions where an increase both the frequency severity drought expected. The patterns mechanisms immediate delayed impacts extreme on vegetation growth remain poorly quantified. Using satellite measurements greenness, in-situ tree-ring records, eddy-covariance CO2 water flux measurements, meta-analyses source use...
Abstract Agreement among instruments is very important for the Multi‐Scale Observation Experiment on Evapotranspiration over heterogeneous land surfaces of The Heihe Watershed Allied Telemetry Experimental Research (HiWATER‐MUSOEXE), particularly in regard to radiation and turbulent flux measurements. Before HiWATER‐MUSOEXE was conducted, 20 eddy covariance (EC) system sets, 18 radiometer seven large aperture scintillometers (LASs) sets were intercompared Gobi desert between 14 24 May 2012....
Abstract Endorheic basins around the world are suffering from water and ecosystem crisis. To pursue sustainable development, quantifying hydrological cycle is fundamentally important. However, knowledge gaps exist in how climate change human activities influence endorheic basins. We used an integrated ecohydrological model, combination with systematic observations, to analyze Heihe River Basin, a typical basin arid region of China. The budget was closed for different landscapes, river...
Abstract Evapotranspiration (ET) is a vital variable for land‐atmosphere interactions that links surface energy balance, water, and carbon cycles. The in situ techniques can measure ET accurately but the observations have limited spatial temporal coverage. Modeling approaches been used to estimate at broad scales, while simulating regional scales remains major challenge. In this study, we upscale from eddy covariance flux tower sites scale with machine learning algorithms. Five algorithms...
Land surface temperature (LST) is a key variable at the land-atmosphere boundary. For many research projects and applications an all-weather LST product moderate spatial resolution (e.g., 1 km) would be highly useful, especially in frequently cloudy areas. Merging thermal infrared (TIR) microwave (MW) observations able to overcome shortcomings of single-source remote sensing derive such LST. However, current merging methods, models adopted for downscaling MW fail quantify effect temporal...
Abstract. The alpine region is important in riverine and watershed ecosystems as a contributor of freshwater, providing stimulating specific habitats for biodiversity. In parallel, recent climate change, human activities other perturbations may disturb hydrological processes eco-functions, creating the need next-generation observational modeling approaches to advance predictive understanding such region. However, several formidable challenges, including cold harsh climate, high altitude...
Abstract [1] Ground-based validation is crucial for ensuring the accuracy of remotely sensed evapotranspiration (RS_ET) and extending its application. This paper proposes an innovative method based on multisource (ET) from ground measurements, with results including assessment, error source analysis, uncertainty analysis process. It a potentially useful approach to evaluate analyze spatiotemporal properties RS_ET at both basin local scales, appropriate validate in diverse resolutions...
Abstract Parameterization of turbulent flux from bare-soil and undercanopy surfaces is imperative for modeling land–atmosphere interactions in arid semiarid regions, where the ground dominant or comparable to canopy-sourced flux. This paper presents major characteristics transfers over seven surfaces. These sites are located arid, semiarid, semihumid regions Asia represent a variety conditions aerodynamic roughness length (z0m; <1 10 mm) sensible heat (from −50 400 W m−2). For each...

Abstract. Cloud parameters (cloud mask, effective particle radius, and liquid/ice water path) are the important inputs in estimating surface solar radiation (SSR). These can be derived from MODIS with high accuracy, but their temporal resolution is too low to obtain high-temporal-resolution SSR retrievals. In order hourly cloud parameters, an artificial neural network (ANN) applied this study directly construct a functional relationship between products Multifunctional Transport Satellite...
