Precipitation is an essential climate and forcing variable for modeling the global water cycle. Particularly, recent Integrated Multi-satellite Retrievals GPM (IMERG) product retrospectively provides unprecedented two decades of high-resolution satellite precipitation estimates. The primary goal this study to examine similarities differences between latest also arguably most popular, IMERG Earl...

The variability of the simulated hydroclimatology of the WaterGAP Global Hydrology Model (WGHM) is analysed. Main object of this study is the ENSO-driven variability of the water storage of South America. The horizontal model resolution amounts to 0.5 degree and it is forced with monthly climate variables for 1961– 1995 of the Tyndall Centre Climate Research Unit dataset (CRU TS 2.0) as a repre...

Declining reservoir storage has raised the specter of the first water shortage on the Lower Colorado River since the completion of Glen Canyon and Hoover Dams. This focusing event spurred modeling efforts to frame alternatives for managing the reservoir system during prolonged droughts. This paper addresses the management challenges that arise when using modeling tools to manage water scarcity ...

Streamflow prediction in ungauged basins provides essential information for water resources planning and management and ecohydrological studies yet remains a fundamental challenge to the hydrological sciences. A methodology is presented for stratifying streamflow regimes of gauged locations, classifying the regimes of ungauged streams, and developing models for predicting a suite of ecologicall...

A large number of recent studies have aimed at understanding short-duration rainfall extremes, due to their impacts on flash floods, landslides and debris flows potential for these worsen with global warming. This has been led in a concerted international effort by the INTENSE Crosscutting Project GEWEX (Global Energy Water Exchanges) Hydroclimatology Panel. Here, we summarize main findings so ...

Abstract. Annual and decadal-scale hydroclimatic variability describes key characteristics that are embedded into climate in situ is of prime importance subtropical regions. The study therefore crucial to understand its manifestation implications for derivatives such as hydrological phenomena water availability. However, the this from modern records limited due their relatively short span, wher...

Soil moisture is a critical hydrological variable that links the terrestrial water, energy and carbon cycles. Global and regional observations of soil moisture are needed to estimate the water and energy fluxes at the land surface, to quantify the net carbon flux in boreal landscapes, to enhance weather and climate forecast skill and to develop improved flood prediction and drought monitoring c...
