Sensitivity and Partitioning in Remote Sensing Based Evapotranspiration Models

Creator:: Talsma, Carl J.
Abstract:: Satellite Based evapotranspiration (ET) models have become a dominant means to estimate large-scale surface fluxes of water. Global and regional ET estimates are important parameters in many climate forecasts and hydrologic models. However, large scale partitioning of ET into soil evaporation, transpiration, and canopy interceptions remains largely unknown and modeled...
