  abstract = {{A} remote sensing-based surface energy balance model is developed to explicitly represent the energy fluxes of four surface components of agricultural fields including bare soil, unstressed green vegetation, non-transpiring green vegetation, and standing senescent vegetation. {S}uch a four-source representation ({SEB}-4{S}) is achieved by a consistent physical interpretation of the edges and vertices of the polygon (named {T}-f(vg) polygon) obtained by plotting surface temperature ({T}) as a function of fractional green vegetation (f(vg)) and the polygon (named {T} - alpha polygon) obtained by plotting {T} as a function of surface albedo (alpha). {T}o test the performance of {SEB}-4{S}, a {T}-alpha image-based model and a {T}-f(vg) image-based model are implemented as benchmarks. {T}he three models are tested over a 16 km by 10 km irrigated area in northwestern {M}exico during the 2007-2008 agricultural season. {I}nput data are composed of {ASTER} ({A}dvanced {S}paceborne {T}hermal {E}mission and {R}eflection {R}adiometer) thermal infrared, {F}ormosat-2 shortwave, and station-based meteorological data. {T}he fluxes simulated by {SEB}-4{S}, the {T}- alpha image-based model, and the {T}-f(vg) image-based model are compared on seven {ASTER} overpass dates with the in situ measurements collected at six locations within the study domain. {T}he evapotranspiration simulated by {SEB}-4{S} is significantly more accurate and robust than that predicted by the models based on a single (either {T}-f(vg) or {T}- alpha) polygon. {T}he improvement provided with {SEB}-4{S} reaches about 100{W} m(-2) at low values and about 100{W} m(-2) at the seasonal peak of evapotranspiration as compared with both the {T}- alpha and {T}-f(vg) image-based models. {SEB}-4{S} can be operationally applied to irrigated agricultural areas using high-resolution solar/thermal remote sensing data, and has potential to further integrate microwave-derived soil moisture as additional constraint on surface soil energy and water fluxes.},
