This study would not have been possible without the careful planning and flying of the University of Wyoming King Air operations group. As mission scientist, LA is particularly thankful for their willingness and ability to carry out these turbulent flights close to the eastern slope of the Sierra Nevada. We particularly thank the following individuals from the University of Wyoming King Air (N2UW): Al Rodi, facility manager; Tom Drew, pilot; Larry Oolman, data and project manager; and from the Gulfstream V: Ron Smith, mission scientist. Georg Mayr’s participation in T-REX was funded by Austrian Science Foundation Grant P18940-N10. Larry Armi’s participation in T-REX was partly funded by The University of California and by Lucky Larry’s Auto Repair; preparation of this publication was partially funded under NSF Grant OCE-1061027. We thank the editor J. Charney and, in particular, one of the reviewers for their careful comments on the manuscript.
