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:

Evaluation of the JULES land surface model in simulating catchment hydrology in Southern Africa
TL;DR: In this paper, the Joint UK Land Environment Simulator (JULES) was configured for a domain covering Southern Africa at a 0.5° resolution and tested on simulated river discharge in sub-catchments of the Orange, Okavango and Zambezi rivers.

A risk-benefit model to simulate vegetation spring onset in response to multi-decadal climate variability: Theoretical basis and applications from the field to the Northern Hemisphere
Qinchuan Xin,Qinchuan Xin +1 more
TL;DR: The Growing Production-Day (GPD) model as discussed by the authors uses the cumulative productivity of a hypothetical reference vegetation cover as the overall benefit and predicts the events of vegetation spring onset when a certain threshold that vegetation invests to mitigate potential hazard damages is reached.

How well are we able to close the water budget at the global scale?
TL;DR: In this article , the authors attempt to close the global water budget using precipitation, evapotranspiration, and runoff data at the catchment scale using two metrics: the Nash-Sutcliffe efficiency (NSE) and the cyclostationary NSE.

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.

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.
