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:

Seasonal evaluation of evapotranspiration fluxes from MODIS satellite and mesoscale model downscaled global reanalysis datasets
Prashant K. Srivastava,Prashant K. Srivastava,Prashant K. Srivastava,Dawei Han,Tanvir Islam,Tanvir Islam,Tanvir Islam,George P. Petropoulos,Manika Gupta,Qiang Dai +9 more
TL;DR: In this article, the seasonal performances of MODIS (MOD16) and Weather Research and Forecasting (WRF) model downscaled global reanalysis datasets, such as ERA interim and NCEP-derived ETo, against ground-based datasets were explored.

Process refinements improve a hydrological model concept applied to the Niger River basin
TL;DR: In this article, a method to improve a process-oriented hydrological model concept applied to another region than it was first developed for is examined, and the results indicate that their approach to separately, sequentially, and iteratively refine processes together with local experts can substantially improve processoriented Hydrological models.

Spatial variation in annual actual evapotranspiration of terrestrial ecosystems in China: Results from eddy covariance measurements
Han Zheng,Guirui Yu,Qiufeng Wang,Xianjin Zhu,Honglin He,Yanfen Wang,Junhui Zhang,Yingnian Li,Liang Zhao,Fenghua Zhao,Peili Shi,Huimin Wang,Junhua Yan,Yiping Zhang +13 more
TL;DR: Wang et al. as mentioned in this paper proposed an empirical equation to describe the spatial patterns of AET in China, which could explain about 84% of the spatial variation in AET of terrestrial ecosystems in China.

Evaluation of Water Use Efficiency Derived from MODIS Products against Eddy Variance Measurements in China
TL;DR: The maximum light use efficiency and fraction of photosynthetically-active radiation (FPAR) were the two most sensitive factors to the estimation of WUE derived from the MODIS GPP and ET algorithms and their contributions to the uncertainty in estimated WUE at both eight-day and annual scales still need to be further quantified.

Climate‐driven uncertainties in modeling terrestrial energy and water fluxes: a site‐level to global‐scale analysis
TL;DR: A land surface model constrained using data from flux tower sites is used, to analyze the biases in ecosystem energy and water fluxes arising due to the use of meteorological reanalysis datasets, and explains several model-data differences in the LE and H fluxes when compared with observationally derived global estimates of these fluxes.

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.
