What controls the error structure in evapotranspiration models?

► We developed statistical models to describe the error structures of 3 different ET products. ► We use these models to conduct variable important and partial dependence analysis. ► Canopy indices EVI and LAI and flux magnitudes were strongest drivers of error. ► The decoupling coefficient and resistance terms were not strong drivers of error. ► Combined flux models or soil moisture estimation may improve ET model performance.
