This research was sponsored by the Defense Advanced Research Projects Agency. We thank Mr. Roger Gibbs of DARPA for his support of this research and development project. We thank Drs. Nathan Platt and Steve Warner of the Institute for Defense Analyses (IDA) for helpful discussions. Field data provided by the following Joint Urban 2003 participants were invaluable for this research effort: NOAA/ARL/FRD, VOLPE, LLNL, LBNL, WSU, UU, DPG, ANL, and PNNL. We thank the following ITT personnel for helping to field the experiment: John Betz, John LeSage, Charles Tobin, Les Mann, Greg Boyle, Leldon Troyer, and Vernon Smith. This manuscript was improved by the helpful comments of three anonymous reviewers.
