Testing the Rationale behind an Assumed Linear Relationship between Evapotranspiration and Land Surface Temperature
Theoretical considerations and empirical evidence indicate a linear relationship between the land surface temperature (Ts) and the corresponding evapotranspiration (ET) rate under spatially constant wind and net energy conditions at a homogeneous vegetated surface. Such a relationship lies at the core of the popular surface energy balance algorithm (SEBAL); the satellite-based energy balance ap...
متن کاملComplementary-relationship-based evapotranspiration mapping (cremap) technique for Hungary
Monthly areal evapotranspiration (ET) rates for 2000–2008 are mapped for Hungary at a spatial scale of about 1-km with the help of MODIS daytime land surface temperature as well as sunshine duration, air temperature and humidity data. Mapping is achieved by a linear transformation of the MODIS daytime land surface temperature values employing the complementary relationship of evaporation. Valid...
متن کاملApplication of MODIS-Based Monthly Evapotranspiration Rates in Runoff Modeling: A Case Study in Nebraska, USA
Daily and monthly flow-rates of the Little Nemaha River in Nebraska were simulated by the lumped-parameter Jakeman-Hornberger as well as a distributed-parameter water-balance accounting procedure for the 2003-2008 and 20002009 periods, respectively, with and without the help of the MODIS-based monthly estimates of evapotranspiration (ET) rates. While the daily lumped-parameter model simulation ...
متن کاملCalibration-Free Evapotranspiration Mapping (CREMAP) results for the High Plains aquifer, USA
The complementary relationship (CR) of evaporation, originally proposed by Bouchet (1963), was subsequently formulated for practical regional-scale ET applications by Brutsaert & Stricker (1979) and Morton et al. (1985). In this study the WREVAP program of Morton et al. (1985) was applied for the estimation of the regional-scale ET rates at monthly periods. Disaggregation of the regional ET val...
متن کاملEstimation of Actual Evapotranspiration, Water productivity, and Irrigation Efficiency of Wheat Fields in Surface and Sprinkler Irrigation Systems Using Remote Sensing
In arid and semi-arid regions, water resource management and optimization of applying irrigation water are particularly important. For optimization of applying irrigation water, the estimated values of actual evapotranspiration are necessary for avoiding excessive or inadequate applying water. The estimation of actual crop evapotranspiration is not possible in large areas using the traditional ...
