Summary of Success: 2013 Presentations

Ogallala Aquifer Program workers met in Amarillo, Texas in March of 2013 to summarize what they have discovered recently during the course of their work. These videos run from ten to thirty minutes and are a good way to learn what is new.


In the News

Reports

Spatial Interpolation of Daily Evapotranspiration (ET) Data in the Texas High Plains   Commonly used interpolation (inverse weighted, spline, and kriging) methods and one new method (machine learning with optimization algorithm(s)) were evaluated for mapping reference ET in the Texas High Plains. Thin-plate spline models increased accuracy of the daily ET maps.  

Statistical and spectral approaches to automate hot and cold pixel selection for surface energy balance based evapotranspiration mapping   A novel statistical-spectral methodology for the selection of hot and cold end member pixels is developed to make the application of single source energy balance models more robust, and successfully applied. Results indicated that the proposed methodology performed better than existing methods.   

About the Ogallala Aquifer

“The Ogallala Initiative is a project funded by the United States Department of Agriculture-Agricultural Research Service (USDA-ARS). The Initiative provides permanent funding for several research projects on water conservation for the Ogallala Aquifer through a consortium between USDA-ARS, Kansas State University, Texas A&M University, Texas Tech University, and West Texas A&M University.”
