Jan 1, 2020 · Ecosystem water use efficiency (WUE), defined as the ratio between gross primary productivity (GPP) and evapotranspiration (ET), is an indicator of the tradeoff between carbon assimilation and water loss that is controlled by climate and ecosystem structure. However, how GPP and ET impact WUE remains poorly understood.

Dec 15, 2022 · Terrestrial evapotranspiration (ET) and photosynthesis (or gross primary productivity, GPP) are indispensable processes in hydrological and carbon cycles at global and regional scales.

Sep 1, 2023 · The classical description of WUE is the gross primary productivity (GPP) per unit of ET. Both GPP and ET can be inferred at the local scale using eddy covariance systems (EC): the gold standard for terrestrial flux monitoring.

Aug 10, 2023 · Increased WUE eco is believed to result from the CO 2 fertilization effect that enhances gross primary productivity (GPP) through photosynthesis and reduces water loss through evapotranspiration (ET) because of declining g s (6, 13).

Jan 17, 2025 · To comprehensively assess and deeply analyze ecosystem responses to accelerated flash droughts, we thoroughly examine the relationship between flash drought intensification rates and the reduction...

Jan 17, 2017 · We evaluated drought impacts on gross primary productivity (GPP), evapotranspiration (ET), and water use efficiency (WUE) of different global terrestrial ecosystems, as well as the drought-resilience of each ecosystem type during the period of 2000 to 2011.

Mar 1, 2019 · Here we estimate 8-day global ET and gross primary production (GPP) at 500 m resolution from July 2002 to December 2017 using a coupled diagnostic biophysical model (called PML-V2) that, built using Google Earth Engine, takes MODIS data (leaf area index, albedo, and emissivity) together with GLDAS meteorological forcing data as model inputs.

Jan 3, 2025 · Using satellite-based estimates of gross primary productivity (GPP) and evapotranspiration (ET), our study investigated the spatiotemporal variations in WUE across China’s terrestrial ecosystems from 2001 to 2020.

Dec 24, 2014 · Gross primary production (GPP) and evapotranspiration (ET) can provide useful information for water and soil resource management, global carbon-water cycle analysis and environmental change monitoring.

Feb 20, 2017 · We calculated water use efficiency (WUE) using measures of gross primary production (GPP) and evapotranspiration (ET) from five years of continuous eddy covariance measurements (2009–2013)...
