This project would have been impossible without the hard work of the UCAR Joint Office for Scientific Support, NCAR's Research Aviation Facility, NOAA's Aircraft Operations Center, and the faculty and staff of the Centro de Ciencias de la Atmósfera at the Universidad Nacional Autónoma de México (CCA-UNAM). The Colorado State University staff on the ship Ron Brown did an excellent job of deploying radiosondes. We also thank Darrel Baumgardner for computing the reflectivity–rainfall relationships for EPIC2001. Ed Zipser and two anonymous reviewers contributed significantly to this paper. Special thanks go to Jay Fein of the National Science Foundation (NSF) and Mike Patterson of NOAA's Office of Global Programs (OGP) for their dedicated support of EPIC2001. NSF and NOAA directly supported the deployment of the two aircraft and the two ships. NOAA's Pacific Marine Environmental Laboratory, which maintains the TAO mooring array, deployed three extra buoys and enhanced the instrumentation on all 95°W moorings for EPIC2001 with the support of NOAA/OGP. This work was sponsored by NSF Grants ATM-0082612, ATM-0082384, and ATM-0002387, and Consejo Nacional de Ciencia Y Tecnología (CONACyT) Grant 33319. The first author spent the academic year 2001–02 at CCA-UNAM in Mexico City with generous support from CONACyT.
