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:

Response of ecosystem productivity to dry/wet conditions indicated by different drought indices.
TL;DR: In this article, the sensitivity of GPP anomalies to five drought indicators (SPI, SPEI, Palmer Drought Severity Index (PDSI), deficit of soil moisture (DSM), and difference between precipitation (P) and evapotranspiration (ET) (D(P-ET)) was examined.

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.
