Scripts created for the 2019 NADEF at A.L. Mickelson Field Station near Cody, WY
Sample data made available from previous fieldweeks or provided by instructors. Please contact Dr. Stockton Maxwell (rmaxwell2@radford.edu) or Dr. Christopher Gentry (gentryc@apsu.edu) before using the data for examples/projects outside of the NADEF Organization.
