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 In this study, we report on the spatial and temporal distribution of seasonal snow depth derived from passive microwave satellite remote-sensing data (e.g. SMMR 1978 to 1987 SMM/ I 2006) in China. We first modified Chang algorithm then validated it using meteorological observation data, considering influences vegetation, wet snow, precipitation, cold desert frozen ground. Furthermore, is dynamically adjusted based variation grain size density. Snow-depth indirectly by MODIS...
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...
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...
Long-term snow depth/snow water equivalent (SWE) products derived from passive microwave remote sensing data are fundamental for climatological and hydrological studies. However, the temporal continuity of is affected by updating or replacement sensors satellite platforms. In this study, we inter-calibrated brightness temperature (Tb) obtained Special Sensor Microwave Imager (SSM/I) Imager/Sounder (SSMI/S). Then, evaluated consistency cover area (SCA) depth Scanning Multichannel Radiometer...
Abstract. Snow cover on the Qinghai–Tibetan Plateau (QTP) plays a significant role in global climate system and is an important water resource for rivers high-elevation region of Asia. At present, passive microwave (PMW) remote sensing data are only efficient way to monitor temporal spatial variations snow depth at large scale. However, existing products show largest uncertainties across QTP. In this study, MODIS fractional product, point, line intense sampling synthesized evaluate accuracy...
Abstract We introduce a multiscale dataset obtained from Heihe Watershed Allied Telemetry Experimental Research (HiWATER) in an oasis-desert area 2012. Upscaling of eco-hydrological processes on heterogeneous surface is grand challenge. Progress this field hindered by the poor availability observations. HiWATER experiment designed to address challenge through instrumentation hierarchically nested scales obtain and multidisciplinary data. The observation system consists flux matrix eddy...
Abstract Unprecedented changes in the climate and environment have been observed three poles, including North Pole, South Third Pole–Tibetan Plateau. Although considerable data collected several observation networks built these polar regions, poles are relatively data-scarce regions due to inaccessible acquisition, high-cost labor, difficult living environments. To address obstacles better understanding unprecedented their effects on global humans, there is a pressing need for curation,...
Abstract Recently, remotely sensed land surface temperature (LST) data have been used to estimate air temperatures because of the sparseness station measurements in remote mountainous areas. Due availability and accuracy Moderate Resolution Imaging Spectroradiometer (MODIS) LST data, use a single term or fixed combination terms (e.g., Terra/Aqua night day), as previous estimation methods, provides only limited practical application. Furthermore, may be affected by different combinations...
Abstract. A long-term Advanced Very High Resolution Radiometer (AVHRR) snow cover extent (SCE) product from 1981 until 2019 over China has been generated by the research team in Northwest Institute of Eco-Environment and Resources (NIEER), Chinese Academy Sciences. The NIEER AVHRR SCE a spatial resolution 5 km daily temporal resolution, it is completely gap-free product, which produced through series processes such as quality control, cloud detection, discrimination, gap-filling (GF)....
Abstract The Tibetan Plateau, known as the world’s “Third Pole” due to its high altitude, is experiencing rapid, intense climate change, similar and even far more than that occurring in Arctic Antarctic. Scientific data sharing very important address challenges of better understanding unprecedented changes Third Pole their impacts on global environment humans. National Plateau Data Center (TPDC, http://data.tpdc.ac.cn ) one first 20 national centers endorsed by Ministry Science Technology...
Abstract Snow depth on the interior of Tibetan Plateau (TP) in state-of-the-art reanalysis products is almost an order magnitude higher than observed. This huge bias stems primarily from excessive snowfall, but inappropriate process representation shallow snow also causes and cover. study investigated issue with respect to parameterization fresh albedo. The characteristics TP snowfall were using ground truth data. usually only some centimeters depth. albedo depends depth, frequently less...
Abstract. Oases and deserts generally act as a landscape matrix mosaic in arid semiarid regions. The significant difference thermal dynamic characteristics between an oasis desert surface will result oasis–desert interaction. Specifically, this refers to the interaction system via exchange of momentum, energy, water, carbon, which can lead series microclimate effects that affect structure atmospheric boundary layer, changes carbon sources sinks oasis, local ecological environment. Therefore,...
Abstract. The climate of the Tibetan Plateau (TP) has experienced substantial changes in recent decades as a result location's susceptibility to global change. observed across TP are closely associated with regional land–atmosphere interactions. Current models and satellites struggle accurately depict interactions; therefore, critical field observations on interactions outlined here provide necessary independent validation data fine-scale process insights for constraining reanalysis...
