Abstract
 Using GRID to Evaluate Different Methods to Estimate Evapotranspiration Track: Water Resources Author(s): Julie Coonrod, Alandren Etlantus, Kristin Vanderbilt The Rio Grande runs through a water scarce region. Portions of the riparian forest are estimated to use as much as 40 percent of the water budget. Thus, accurate estimates of riparian evapotranspiration (ET) are imperative to water managers. Three-dimensional eddy covariance towers have been established and maintained throughout the Middle Rio Grande Valley to measure ET. The tower data has been used to scale ET data to the corridor using remote-sensing imagery. Alternatively, a number of researchers have used imagery with energy balance methods to estimate ET in the corridor. Researchers using the different methods to estimate ET for the corridor were asked to supply their ET results in a GRID format to enable the use of ArcGIS for calculation of difference grids. The difference grids highlight where the methods compute the most similar/different results enabling further development of ET estimation methods.
