Improvements to a MODIS global terrestrial evapotranspiration algorithm
TLDR
In this article, an improved version of the global evapotranspiration (ET) algorithm based on MODIS and global meteorology data has been proposed, which simplifies the calculation of vegetation cover fraction, calculating ET as the sum of daytime and nighttime components, adding soil heat flux calculation, improving estimates of stomatal conductance, aerodynamic resistance and boundary layer resistance, separating dry canopy surface from the wet and dividing soil surface into saturated wet surface and moist surface.About:

Evapotranspiration Variability and Its Association with Vegetation Dynamics in the Nile Basin, 2002-2011
TL;DR: Analysis of the relationship of ET with climate, vegetation and land cover in the Nile Basin during 2002–2011 revealed that >50% of the study area exhibited negative ET anomalies for 7 years (2009, driest), while >60% exhibited positive ET anomaly for 3 years (2007, wettest).

Satellite-based Evapotranspiration in Hydrological Model Calibration
TL;DR: This study confirms that with reasonable precipitation input, the ETRS-based spatially distributed calibration can efficiently tune parameters for better ET and streamflow simulations and outperform the baseline simulations in 90% of the river basins using model parameters from the best ETRs calibration runs.

How reliable are the evapotranspiration estimates by Soil and Water Assessment Tool (SWAT) and Variable Infiltration Capacity (VIC) models for catchment-scale drought assessment and irrigation planning?
TL;DR: In this paper, the authors evaluate the usability of these indirect evapotranspiration estimation methods with reference to the moisture-stress specific FAO-56 Penman-Monteith (PM) equation for catchment-scale drought and irrigation planning in a real paddy-dominated integrated reservoir-catchment command.

Overview of the radiometric and biophysical performance of the MODIS vegetation indices
TL;DR: In this paper, the authors evaluated the performance and validity of the MODIS vegetation indices (VI), the normalized difference vegetation index (NDVI) and enhanced vegetation index(EVI), produced at 1-km and 500-m resolutions and 16-day compositing periods.
