Growing Degree Days & Evapotranspiration Data

ET Resources

As part of the Nebraska Agricultural Water Management Network, data is provided by growers, consultants, NRD staff, Extension educators, and weather stations. Using the Nebraska map simply click on a site near your location to go to a page that includes the weekly ETgage change along with weekly rainfall amounts. The ETgage change along with your crop's stage of growth can be used to estimate crop water use. NAWMN.

See table below for Evapotranspiration & GDD for more than 20 Nebraska sites.

GDD Resources

U2U Corn GDD Decision Support Tool. Developed by specialists at several Midwest universities, including UNL, as part of the Useful to Usable climate data project, this tool puts current conditions into a 30-year historical perspective and offers trend projections through the end of the calendar year.
Nebraska GDD data (below, in table format) is provided by the High Plains Regional Climate Center. It offers GDD for multiple crops and crop emergence dates for sites across Nebraska.
