Resumo A principal limitação para estudos climáticos em escala regional no Brasil é a disponibilidade de dados meteorológicos observados termos quantidade, qualidade e da sua distribuição espacial. Dados velocidade vento reanálises climáticas são utilizadas diversos modelagem climatológica hidrológica, porém destes sobre o território brasileiro ainda desconhecida considerando produtos diária re...

Compound droughts and hot events (or droughts) have attracted increasing attention due to their far-reaching impacts. Previous studies on these mostly focused the concurrence of meteorological extremes. The compound agricultural (CADHEs), which direct impacts production, received limited variability driving factors. In this study, we defined CADHEs based summer temperature soil moisture from Gl...

Abstract. Soil moisture and soil temperature (SMST) are important state variables for quantifying the exchange of heat water between land atmosphere. Yet, long-term, regional-scale in situ SMST measurements scarce on Tibetan Plateau (TP), with even fewer available multiple depths. Tibet-Obs is such a observatory TP that has been established 10 years ago includes three monitoring networks, i.e. ...

The Gravity Recovery and Climate Experiment (GRACE) mission is able to observe the global large-scale mass and water cycle for the first time with unprecedented spatial and temporal resolution. However, no other time-varying gravity fields validate GRACE. Furthermore, the C20 of GRACE is poor, and no GRACE data are available before 2002 and there will likely be a gap between the GRACE and GRACE...

Soil moisture is the vital component of the hydrological cycle and its variability is largely uncertain in the upcoming decades. In this paper the future projections of soil moisture changes over South Asia have been analyzed on both annual and seasonal basis from 2020-2050. The comparison of 24 CMIP5 (Coupled Model Inter comparison Project Phase 5) models with GLDAS (Global Lad Data Assimilati...

The Djeffara plain, extending over Tunisia and Libya (48,000km 2 ), experiences unsustainable exploitation of groundwater, the severity which needs to be determined. Here, we used data from Gravity Recovery Climate Experiment (GRACE) Global Land Data Assimilation System (GLDAS) assess groundwater storage variation (ΔGWS) for period 2002–2016. ΔGWS values, downscaled a 0.5°×0.5° grid using pumpi...

Accurate precipitation data is essential for any hydrometeorological study, particularly calibration and simulation of hydrological models. In this paper, we evaluate the two different reanalysis products (the ERA5 GLDAS), satellite-based (TRMM 3B42 CHIRPS) over La Sierra river basins in Southern Mexico, on regional daily time scales, from 2008 to 2010. We compare collocated gridded against in-...

The hydrological processes in the Three-River Headwaters Region (TRHR), which is located Qinghai-Tibetan Plateau and includes Yangtze River Headwater (YARHR), Yellow (YERHR), Lantsang (LARHR), have changed under climate warming. Based on multi-source data, spatial temporal changes precipitation, evapotranspiration, soil water storage, glacier melt, snowmelt runoff from 1982 to 2014 were compreh...

Water is essential for irrigation, drinking and industrial purposes from global to the regional scale. The groundwater considered a significant water resource specifically in regions where surface not sufficient. Therefore, research problem focused on district-wise sustainable management due urbanization. number of impervious areas like roofing built-up areas, concrete asphalt road were increas...
