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:

Effects of grazing on leaf area index, fractional cover and evapotranspiration by a desert phreatophyte community at a former uranium mill site on the Colorado Plateau.
TL;DR: It is shown that ET is approximately equal to annual precipitation at the site, but when ATCA and SAVE are protected from grazing they can develop high f(c) and LAI values, and ET can exceed annual precipitation, with the excess coming from groundwater discharge.
Journal ArticleDOI
Comparing potential recharge estimates from three Land Surface Models across the western US
TL;DR: The results highlight that LSMs have the potential to capture the spatial and temporal patterns as well as seasonality of recharge at large scales and can be used as a tool for estimating future recharge rates in data limited regions.

Analysis of variations and controls of evapotranspiration over major Indian River Basins (1982-2014).
Aarti Soni,Tajdarul H. Syed +1 more
TL;DR: This study analyses long-term estimates of evapotranspiration (ET) over four major river basins of India with the primary objective of understanding the factors controlling its space-time variability and reveals that ET variance is largely controlled by the availability of water.
Journal ArticleDOI
Estimating land surface variables and sensitivity analysis for CLM and VIC simulations using remote sensing products
TL;DR: The results from this study are conducive to improvements in models and satellite based characterization of water and energy fluxes, especially at rugged terrain with high elevation, where observational experiments are difficult to conduct.

Validity of Five Satellite-Based Latent Heat Flux Algorithms for Semi-arid Ecosystems
Fei Feng,Jiquan Chen,Xianglan Li,Yunjun Yao,Shunlin Liang,Shunlin Liang,Meng Liu,Meng Liu,Nannan Zhang,Yang Guo,Jian Yu,Minmin Sun +11 more
TL;DR: Empirical parameters in the structure algorithms of MOD16 and RRS, and calibrated coefficients of the UMD algorithm may be the cause of the reduced performance of these LE algorithms over semiarid ecosystems.

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.

On the Assessment of Surface Heat Flux and Evaporation Using Large-Scale Parameters
C. H. B. Priestley,R. J. Taylor +1 more
TL;DR: In this article, the large-scale parameterization of the surface fluxes of sensible and latent heat is properly expressed in terms of energetic considerations over land while formulas of the bulk aerodynamic type are most suitahle over the sea.
Journal ArticleDOI
Summarizing multiple aspects of model performance in a single diagram
TL;DR: In this article, a diagram has been devised that can provide a concise statistical summary of how well patterns match each other in terms of their correlation, their root-mean-square difference, and the ratio of their variances.

TL;DR: The first worldwide synthesis to jointly consider human and biodiversity perspectives on water security using a spatial framework that quantifies multiple stressors and accounts for downstream impacts is presented.
Journal Article
Evaporation and environment.
TL;DR: Progress towards a reconciliation of parallel concepts in meteorology and physiology is described, which stresses the importance of physiological restraint on the rate of transpiration from an irrigated field surrounded by dry land.
