The authors wish to thank Marvin Wesely and Richard Coulter of Argonne National Laboratory, and Tom Horst and Tony Delany of NCAR for useful discussions, and Chin-Hoh Moeng, Greg Poulos, Joe Alfieri, and three anonymous reviewers for reviewing the paper and offering useful comments and useful background material. Finally, Larry Mahrt of Oregon State University and Ron Smith of Yale University provided helpful input. The comments from the three reviewers were useful and led to a better product. Kris Conrad helped prepare some of the figures. We also gratefully acknowledge NCAR ISFF for installing and maintaining the surface flux stations through CASES-97, and helping with the data afterward, and for collecting, correcting, and archiving the radiosonde data; and the Atmospheric Boundary Layer Experiments group at Argonne National Laboratory for installation and maintenance of wind profiling systems and archiving data afterward, and for answering our questions about the data. KI's support during this work was from the NCAR MMM CaSPP Program; RLG's support was from NSF-ATM Grant 9981811, and MWR's work was supported in part by the NCAR/MMM visitor's program.
