Satellite time series data reveal interannual and seasonal spatiotemporal evapotranspiration patterns in China in response to effect factors
TL;DR: Wang et al. as discussed by the authors evaluated the performance of MOD16 (the MODIS global ET product) data under different conditions, and then the MOD16 data were used to analyze the interannual and seasonal variability of ET and its spatial distribution characteristics in China.
Journal ArticleDOI
Long time series of daily evapotranspiration in China based on the SEBAL model and multisource images and validation
TL;DR: Cheng et al. as mentioned in this paper used multisource images to generate a long-time-series (2001-2018) daily evapotranspiration (ET) product with a spatial resolution of 1.

Parameter estimation of coupled water and energy balance models based on stationary constraints of surface states
TL;DR: In this paper, conditional averaging of the modeled fluxes with respect to soil moisture and temperature is used to estimate the parameters of a land surface water and energy balance model and then use the estimated parameters to partition net radiation into latent, sensible, and ground heat fluxes and precipitation into evapotranspiration and drainage plus runoff.

A simple model for spatial disaggregation of evaporative fraction: Comparative study with thermal sharpened land surface temperature data over India
TL;DR: In this article, a simple model (disaggregation of evaporative fraction (DEFrac)) based on the observed relationship between EF and the normalized difference vegetation index is proposed to spatially disaggregate EF.

TL;DR: In this article, the authors developed methods and protocols for water productivity mapping (WPM) using remote sensing data at multiple resolutions and scales in conjunction with field-plot data, and demonstrated the methods for mapping water productivity (WP) using data from Quickbird 2.44m, Indian Remote Sensing (IRS) Resoursesat-1 23.5m, Landsat-7 30m, and Moderate Resolution Imaging Spectroradiometer (MODIS) 250m and 500m.

The Interpretation of the Variations in Leaf Water Potential and Stomatal Conductance Found in Canopies in the Field
TL;DR: In this paper, the stomatal conductance of illuminated leaves is a function of current levels of temperature, vapour pressure deficit, leaf water potential (really turgor pressure) and ambient CO $_2$ concentration and when plotted against any one of these variables a scatter diagram results.

Piers J. Sellers,David A. Randall,G. J. Collatz,Joseph A. Berry,Christopher B. Field,D. A. Dazlich,Changan Zhang,G.D. Collelo,Lahouari Bounoua +8 more
TL;DR: In this paper, a revised version of the Simple Biosphere model (SiB2) is presented, incorporating a realistic canopy photosynthesis-conductance model to describe the simultaneous transfer of CO2 and water vapor into and out of the vegetation, respectively.

Footprint prediction of scalar fluxes from analytical solutions of the diffusion equation
TL;DR: The use of analytical solutions of the diffusion equation for "footprint prediction" is explored in this paper, where the upwind area most likely to affect a downwind flux measurement at a given height is compared.

Wheat canopy temperature: A practical tool for evaluating water requirements
TL;DR: In this paper, the authors used a sliding cubic smoothing technique to calculate daily water contents and thus water depletion rates for the entire growing season and used this to predict water use by wheat in six differentially irrigated plots.
