Long-term persistence in discharge time series of mountainous catchments in the Elbe River basin [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2020
Statistical detection of trends in hydrometeorological time series is a crucial task when revealing how river systems react to environmental and human-induced changes.

Strong Influence of Irrigation on Water Budget and Land Surface Temperature in Indian Subcontinental River Basins

open access: yesJournal of Geophysical Research - Atmospheres, 2019
Irrigation modulates the terrestrial water budget in intensively irrigated regions. However, the influence of irrigation on water budget and land surface temperature (LST) has not been quantified in Indian subcontinental river basins.

Flooding-Driven Greenhouse Gas Emissions From Global Upland Croplands. [PDF]

open access: yesAdv Sci (Weinh)
Temporary flooding of upland croplands releases nitrous oxide, carbon dioxide, and methane. Field measurements combined with a global literature synthesis yield a global estimate of 63.3 teragrams of carbon dioxide equivalent per year for diffusive emissions from flooded upland croplands.

Challenges in applying water budget framework for estimating groundwater storage changes from GRACE observations

open access: yesJournal of Hydrology
The application of a water budget framework to isolate Gravity Recovery and Climate Experiment (GRACE) groundwater storage anomalies (GRACE-GWA) from GRACE terrestrial water storage anomalies (GRACE-TWSA) is hindered by the lack of direct observations of

Estimation of Water Budget Components of the Sakarya River Basin by Using the WEAP-PGM Model

open access: yesWater, 2019
The use of water resources has increased with rapid population growth, industrial development, and agricultural activities. Besides, the problem might increase with the potential climate change impacts on water quantity.

The Water and Energy Budget of the Arctic Atmosphere [PDF]

open access: yesJournal of Climate, 2005
Abstract The Arctic plays a major role in the global circulation, and its water and energy budget is not as well explored as that in other regions of the world. The aim of this study is to calculate the climatological mean water and energy fluxes depending on the season and on the North Atlantic Oscillation (NAO) through the lower ...

Implications of Improved Representation of Convection for the East Africa Water Budget Using a Convection-Permitting Model

open access: yesJournal of Climate, 2019
The precipitation and diabatic heating resulting from moist convection make it a key component of the atmospheric water budget in the tropics. With convective parameterization being a known source of uncertainty in global models, convection-permitting (

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

open access: yesAdvanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Optimizing NiMo Electrocatalyst Coatings for Hydrogen Evolution in Alkaline Electrolysis With The Machine Learning‐Guided Autonomous Platform CatBot

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a closed‐loop optimization workflow integrating CatBot, an automated synthesis and testing system, to discover NiMo hydrogen‐evolution catalysts. CatBot synthesised and evaluated 228 unique samples, identifying the best performing catalysts for transfer to nickel‐foam electrodes. The best candidate is highly active, reaching 1 Acm−2${
