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:

A Quantitative Inspection on Spatio-Temporal Variation of Remote Sensing-Based Estimates of Land Surface Evapotranspiration in South Asia
Ainong Li,Wei Zhao,Wei Deng +2 more
TL;DR: The result indicated that the semi-arid or arid areas in the northwest had the lowest average daily ET with a big fluctuation in the monsoon season, while the sites in the Indo-Gangetic Plain and in southern India has bigger daily ET due to a large water supplement.

An automatic tool for reconstructing monthly time-series of hydro-climatic variables at ungauged basins
TL;DR: A GIS-based model for a rapid and reliable assessment of monthly time-series of several key hydro-climatic variables at the basin scale, is developed as plug-in and applied to the entire region of Sicily.

Exploring the urban water-energy-food nexus under environmental hazards within the Nile
Nadir Ahmed Elagib,Suhair A. Gayoum Saad,Mohammed Basheer,Abbas E. Rahma,Abbas E. Rahma,Emmanuela Darius Lado Gore +5 more
TL;DR: In this article, a case study was conducted for the capital of Sudan, Khartoum, at the confluence of the White Nile and the Blue Nile for illustration, and the results were based on analyses of river flow and water turbidity data, field observations, and an interview of farmers practicing irrigated agriculture, and hydropower modeling.

On the use of a snow aridity index to predict remotely sensed forest productivity in the presence of bark beetle disturbance
TL;DR: In this article, the authors used multiple sources of remotely sensed and ground-based information to evaluate the spatio-temporal variability of snowpack accumulation, potential evapotranspiration (PET), and Normalized Difference Vegetation Index (NDVI).

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.

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.
