The authors acknowledge the Iowa Energy Center for providing wind and temperature data obtained during performance of its “Tall Tower Investigation of Midwest Wind Patterns” project that was funded, in part, with a grant from the U.S. Department of Energy for the State Energy Program. Partial support was provided by the National Science Foundation under the State of Iowa EPSCoR Grant 1101284.
