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:

An Investigation on the Closure of the Water Budget Methods Over Volta Basin Using Multi-Satellite Data
Vagner G. Ferreira,Zibrila Asiah +1 more
TL;DR: In this paper, the authors assess the closure of the water budget methods [i.e., terrestrial water budget (TWB) and the coupled atmospheric-terrestrial water budget(ATWB)] as well as the control of total water storage gain over Volta Basin of West Africa.

Developing a Gap-Filling Algorithm Using DNN for the Ts-VI Triangle Model to Obtain Temporally Continuous Daily Actual Evapotranspiration in an Arid Area of China
TL;DR: A gap-filling algorithm (TSVI_DNN) using a deep neural network ( DNN) with the Ts-VI triangle model is presented to obtain temporally continuous daily actual ET at regional scale to contribute to enhanced water resource management in arid areas.

Biogeophysical forcing of land-use changes on local temperatures across different climate regimes in China.
TL;DR: In this paper, the authors integrated field observations, satellite-retrieved data, and a conceptual land surface energy balance model to provide new evidence to fill the knowledge gap concerning how regional warming or cooling is affected by the three main types of land use changes (afforestation, cropland expansion, and urbanization) in different climate zones of China.

Variation of dissolved organic carbon transported by two Chinese rivers: The Changjiang River and Yellow River.
TL;DR: This study was the first to simulate the monthly DOC concentrations at the Datong Hydrometric Station for the Changjiang River and at the Lijin hydrometric station for the Yellow River from 2000 to 2013 using a multilayer back-propagation neural network (MBPNN), along with basin remote-sensing products and river in situ data.

Estimation of Global Irrigation Water Use by the Integration of Multiple Satellite Observations
TL;DR: In this paper , a comprehensive framework was proposed to couple the different processes associated with irrigation and integrate multiple satellite observations to estimate the global IWU. The results showed reasonable correlation with the survey-based irrigation water withdrawal in states of the US (bias = −0.42 km3), provinces of China (basing = −3.10 km3) and country statistics from the Food and Agriculture Organization (b bias = −10.84 km3).

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.

Evaporation and environment.
TL;DR: Progress towards a reconciliation of parallel concepts in meteorology and physiology is described, which stresses the importance of physiological restraint on the rate of transpiration from an irrigated field surrounded by dry land.
