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:

Variability in evaporation across the Canadian Prairie region during drought and non-drought periods
TL;DR: In this article, the cold regions hydrological model (CRHM) is applied to calculate estimates of actual evaporation at point locations which had sufficient hourly measurements, which can be applied to constrain land surface parameterization schemes.

Improving Budyko curve‐based estimates of long‐term water partitioning using hydrologic signatures from GRACE
TL;DR: In this article, a group of linear models embodying two alternate hypotheses that departures can be predicted by Taylor series expansion based on the deviation of physical characteristics (seasonality, snow fraction, and vegetation index) from reference conditions and surrogate indicators covarying with E, e.g., A/P, were fitted using a mesoscale USA data set (HUC4) and then evaluated using world data sets and USA basins 1000 km2 and, according to comparison with other global data sets, with GRACE error as estimates of uncertainty.

Measurement and Partitioning of Evapotranspiration for Application to Vadose Zone Studies
TL;DR: In this paper, the authors discuss advances in partitioning the energy balance between canopy and soil using remote sensing and conclude that the flux variance partitioning with raw eddy covariance data and the two-source energy balance approaches with remote sensing platforms may have the greatest potential for partitioning evapotranspiration, in part because large public repositories of eddy coefficients and satellite data could be readily reprocessed to partition ET.

Trophic interactions among vertebrate guilds and plants shape global patterns in species diversity.
Jian Zhang,Jian Zhang,Hong Qian,Marco Girardello,Vincent Pellissier,Scott E. Nielsen,Jens-Christian Svenning +6 more
TL;DR: It is demonstrated that, after accounting for environmental drivers, large-scale species richness patterns in plant and vertebrate taxa consistently support trophic interactions playing a major role in shaping global patterns in biodiversity, and suggested that top-down forces often play strong complementary roles relative to bottom-up drivers in structuring biodiversity patterns across trophIC levels.

Environmental livelihood security in Southeast Asia and Oceania: A water-energy-food-livelihoods nexus approach for spatially assessing change [White paper]
Eloise M. Biggs,Bryan Boruff,Eleanor Bruce,John Duncan,B. J. Haworth,Stephanie Duce,Julia Horsley,Jayne Curnow,Andreas Neef,Kellie McNeill,Natasha Pauli,F.F. van Ogtrop,Y. Imanari +12 more
TL;DR: In this article, the authors present the first conceptualization of "environmental livelihood security" which combines the nexus perspective with sustainable livelihoods, addressing the need for explicit inclusion of livelihoods within the environment nexus (water-energy-food security), not only responding to literature gaps but also addressing emerging dialogue from existing nexus consortia.

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.

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.
