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:

Application of a Remote Sensing Method for Estimating Monthly Blue Water Evapotranspiration in Irrigated Agriculture
TL;DR: The preliminary results show that the temporal signature of the total ETb allows seasonal patterns to be distinguished within a year and inter-annual ETb dynamics, and an increase of groundwater use was observed at the expense of surface water use.

An intercomparison of satellite-based daily evapotranspiration estimates under different eco-climatic regions in South Africa
Nobuhle P. Majozi,Chris M. Mannaerts,Abel Ramoelo,Renaud Mathieu,Azwitamisi E. Mudau,Wouter Verhoef +5 more
TL;DR: This research investigated the performance of three satellite-based ET algorithms and two global products, namely land surface temperature/vegetation index, Penman–Monteith (PM), and the Meteosat Second Generation ET (MET) and the Global Land-surface Evaporation: the Amsterdam Methodology (GLEAM)global products, in two eco-regions of South Africa.

Optimizing a remote sensing production efficiency model for macro-scale GPP and yield estimation in agroecosystems
TL;DR: In this article, the authors proposed a new PEM that addresses deficiencies for macro-scale application: Production Efficiency Model Optimized for Crops (PEMOC), which was developed by optimizing functions from the literature with GPP estimated by eddy covariance flux towers in the United States.

Spatiotemporal distribution and national measurement of the global carbonate carbon sink.
Huiwen Li,Shijie Wang,Xiaoyong Bai,Weijun Luo,Hong Tang,Yue Cao,Luhua Wu,Fei Chen,Qin Li,Cheng Zeng,Mingming Wang +10 more
TL;DR: This research estimated the magnitudes, spatial distributions, variations and contributions to the global carbon budget of the CCS in a higher spatiotemporal representativeness and expandability way, which can help us further reveal and support the understanding of global rock weathering carbon sequestration, terrestrial carbon sink system and global carbon cycle dynamics.

Implications of water management representations for watershed hydrologic modeling in the Yakima River basin
TL;DR: In this paper, the authors evaluated streamflow simulations in the Yakima River basin (YRB) based on different reservoir operation and irrigation schemes and found that simulated streamflow with the reservoir operation scheme optimized by the SWAT model better reproduced measured streamflow than the simulation using the default SWAT reservoir operation.

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.
