Socioeconomic Deprivation Weighs Heavily on Liver Fibrosis and Mortality After Hepatitis C Cure (ANRS CO22 Hepather)

open access: yesJournal of Viral Hepatitis, Volume 31, Issue 12, Page 830-846, December 2024.
ABSTRACT Although Hepatitis C virus (HCV) infection can be cured with direct‐acting antivirals (DAA), some cured patients face a serious risk of advanced liver damage and early mortality. In order to avoid these two negative health outcomes, it is important to identify and assess related risk factors.

Assessing Nitrate Leaching During Drought and Extreme Precipitation: Exploring Deep Vadose‐Zone Monitoring, Groundwater Observations, and Field Mass Balance

open access: yesWater Resources Research, Volume 60, Issue 11, November 2024.
Abstract The increasing concern over agricultural practices' impact on groundwater quality necessitates comprehensive studies to evaluate and compare monitoring strategies for nitrate leaching. This work addresses this imperative by examining three methodologies: deep vadose‐zone monitoring, shallow groundwater intensive monitoring, and field‐level ...

Assimilation of Sentinel‐Based Leaf Area Index for Modeling Surface‐Ground Water Interactions in Irrigation Districts

open access: yesWater Resources Research, Volume 60, Issue 10, October 2024.
Abstract Vegetation‐related processes, such as evapotranspiration (ET), irrigation water withdrawal, and groundwater recharge, are influencing surface water (SW)—groundwater (GW) interaction in irrigation districts. Meanwhile, conventional numerical models of SW‐GW interaction are not developed based on satellite‐based observations of vegetation ...

Cloud Radiative Feedback to the Large‐Scale Atmospheric Circulation Greatly Reduces Monsoon‐Season Wet Bias Over the Tibetan Plateau in Climate Modeling

open access: yesGeophysical Research Letters, Volume 51, Issue 14, 28 July 2024.
Abstract Over‐estimation of summer precipitation over the Tibetan Plateau (TP) is a well‐known and persistent problem in most climate models. This study demonstrates the impact of a Gaussian Probability Density Function cloud fraction scheme on rainfall simulations using the Weather Research and Forecasting model. It is found that this scheme in both 0.

Remote Sensing and GIS Techniques for Irrigation Water Management in North Delta of Egypt under Water Scarcity Conditions [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering
Remote sensing and GIS are effective for assessing crop water use and estimating evapotranspiration rates. This study aims to improve water management planning on selected farms by determining the best estimates of actual evapotranspiration (ETa).

Variabilidade local e regional da evapotranspiração estimada pelo algoritmo SEBAL Local and regional variability of evapotranspiration estimated by SEBAL algorithm

open access: yesEngenharia Agrícola, 2010
Em face da importância em conhecer a evapotranspiração (ET) para uso racional da água na irrigação no contexto atual de escassez desse recurso, algoritmos de estimativa da ET a nível regional foram desenvolvidos utilizando-se de ferramentas de sensoriamento remoto.

Improved 30‐m Evapotranspiration Estimates Over 145 Eddy Covariance Sites in the Contiguous United States: The Role of ECOSTRESS, Harmonized Landsat Sentinel‐2 Imagery, Climate Reanalysis, and Deep Neural Network Postprocessing

open access: yesWater Resources Research, Volume 60, Issue 4, April 2024.
Abstract This study developed and evaluated 30‐m daily evapotranspiration (ET) estimates using the Priestley‐Taylor Jet Propulsion Laboratory (PT‐JPL) model with ECOSTRESS, Moderate MODIS, harmonized Landsat Sentinel‐2 (HLS) imagery, ERA5‐Land reanalysis, and eddy covariance measurements. The new daily 30‐m ET showed significantly improved performance (
