Journal: :Water 2021

Terrestrial evapotranspiration (ET) over the Tibetan Plateau (TP) exerts considerable impacts on local climate and water cycle. However, high-altitude, mountainous areas TP pose a challenge for field observations. To finely capture its ET characteristics, we employed dynamical downscaling modeling (DDM) with 28 km resolution convection-permitting (CPM) 4 in normal climatology year, 2014. The be...

Abstract Water is an important factor that affects local ecological environments, especially in drylands. The hydrological cycle and vegetation dynamics Central Asia (CA) have been severely affected by climate change. In this study, we employed data from Gravity Recovery Climate Experiment (GRACE), Global Land Data Assimilation System (GLDAS), Evaporation Amsterdam Model, Research Unit to analy...

Height variations caused by mass change make an important contribution to the tectonic uplift of Qinghai-Tibet Plateau (QTP). To study deformation attributable hydrological loading and real potential vertical motion, satellite gravity data from Gravity Recovery Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) with Global Land Data Assimilation System (GLDAS) Positioning (GPS) are adopted e...

Soil temperature is a crucial parameter in surface emissions of carbon, water, and energy exchanges. This study utilized the soil 836 national basic meteorological observing stations over China to evaluate three products. data from Meteorology Administration Land Data Assimilation System (CLDAS), European Centre for Medium-Range Weather Forecasts (ERA-Interim), Global (GLDAS) during 2017 are ev...

Abstract. Water stored beneath the Earth’s surface, known as groundwater is a major water supply for living things. The increase in human population leading to high urban development and industrial needs Malaysia has made use of more critical. current issue faced by limitation freshwater source from dam resulting increasing demand gather fresh groundwater; hence, crucial exploitation groundwate...

This paper comprehensively analyzes the effect of surface mass loading on GPS height time series in terms weighted root mean square (WRMS), annual timescale, velocity and noise properties. Considering complexity hydrological process, we adopt same atmospheric nontidal ocean estimated from TUGO-m barotropic model (ATMMO) different loadings Global Land Data Assimilation System (GLDAS) Surface Dis...

در سال  های اخیر مقوله خشکسالی به یک معضل جهانی به ویژه در مناطق خشک و نیمه خشک جهان تبدیل شده است. بدون شک شناسایی و پایش خشکسالی را می  توان گامی مهم در جهت مبارزه و کاهش خسارات ناشی از آن دانست. رطوبت خاک و تغییرات زمانی و مکانی آن یکی از مهمترین متغیرهای محیطی است که به دلیل اندازه  گیری  های دشوار، پرهزینه و وق تگیر میدانی، تاکنون به طور گسترده در شاخص  های خشکسالی استفاده نشده است...
