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...
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...
Foliage and soil temperatures are key variables for assessing the exchanges of turbulent heat fluxes between vegetated land atmosphere. Using multiple-view-angle thermal-infrared (TIR) observations, vegetation may be retrieved. However, particularly sparsely areas, component in sun shade very different depending on solar radiation, physical properties surface, meteorological conditions. This interfere with a correct retrieval temperatures, but it might also yield extra information related to...
Abstract Remote sensing of solar‐induced fluorescence (SIF) opens a new window for quantifying key ecological variable, the terrestrial ecosystem gross primary production (GPP), because revealed strong SIF–GPP correlation. However, similar to many other remotely sensed metrics, SIF observations suffer from sun‐sensor geometry effects, which may have important impacts on relationship but remain poorly understood. Here we used SIF, globally distributed tower GPP data, and mechanistic model...
Over the past 2 to 3 decades, Chinese forests are estimated act as a large carbon sink, yet magnitude and spatial patterns of this sink differ considerably among studies. Using microwave (L- X-band vegetation optical depth [VOD]) (normalized difference index, leaf area tree cover) remote-sensing products, study compared live woody aboveground biomass (AGC) dynamics over China between 2013 2019. Our results showed that cover has highest consistency with published AGC maps (mean correlation...
Heterogeneous terrain significantly complicates signals received by airborne or satellite sensors. It has been demonstrated that both solar direct beam and diffuse skylight illumination conditions are significant factors influencing the anisotropy of reflectance over mountainous areas. Several models methods have developed to account for topographic effects on surface at pixel level in remote sensing. However, subtopographic generally neglected low-spatial-resolution pixels due complex law...
The purpose of the study was to acquire source and evaluate risk posed by heavy metals in road dust steel industrial city (Anshan), Liaoning, Northeast China. Potential ecological index (RI), pollution (PI) geo-accumulation (Igeo) were applied metal level, carcinogenic (RI) hazard (HI) calculated estimate human health risk. geographic information system maps clearly reveal hot spots spatial distribution. Principle component analysis (PCA) cluster (CA) classified into three groups. Zn Pb...
Moderate-high resolution satellite missions provide an opportunity to capture subtle spatial variability in lakes; however, the sparsity of time series for individual instruments cannot monitor temporal variation lake environment. To date, studies on joint observations chlorophyll-a (Chl-a) inland lakes from multiple have been poorly reported. Here, we generated a harmonized Chl-a dataset Yunnan–Guizhou Plateau China 2013 2022 by Landsat 8/9 and Sentinel-2A/B virtual constellation. This...
Abstract The quality of surface reflectance product is fundamentally important to ensure the information extracted from downstream products can be trusted. However, ground validation satellite challenging, because “truth” on a coarse grid scale based sparse measurements subject uncertainty due spatial heterogeneity. Based high‐resolution numerical simulation, this study quantifies influence heterogeneity in different sampling cases (i.e., number and positions sampled plots). effect very...
Topography complicates the modeling and retrieval of land surface albedo due to shadow effects redistribution incident radiation. Neglecting topographic may lead a significant bias when estimating over single slope. However, for rugged terrain, comprehensive systematic investigation on is currently ongoing. Accurately terrain presents challenge in remote sensing applications. In this paper, we focused development simplified estimation method snow-free at 1-km scale based 30-m fine-scale...
Radiometric measurements in the Thermal Infrared (TIR) domain exhibit an angular variation over most surface types, known as Radiation Directionality (TRD) phenomenon. A primary objective of ongoing development TRD physical models is to perform a correction effects obtain comparable land temperature products. In practice, it advised handle only having limited number input parameters for purpose operational applications. The use semi-empirical kernel-driven (KDMs) appears be good tradeoff...
