We wish to acknowledge the efforts of the flight crew members of the P-3 aircraft from NOAA’s Office of Aircraft Operations in Tampa, Florida. Their dedication and enthusiastic participation in the long 4-month TOGA COARE project from the remote base of operations at Honiara, Solomon Islands, made the collection of data in or near hazardous weather conditions possible. Mr. Robert Hueftle was instrumental in development of the Doppler editing and display software, Dr. Bradley Smull helped execute the dual P-3 flight patterns as Chief Scientist on N43, Mr. Thomas Shepherd and Ms. Diana Bartels operated the Doppler radars on the two P-3 aircraft, Dr. Thomas Matejka was instrumental in the design of the quad-Doppler flight strategies and also developed the methodology for synthesizing the horizontal and vertical winds from the radial velocity data, Dr. John Daugherty prepared the P-3 radar composites and managed most of the datasets, and Mr. David Johnson edited most of the P-3 Doppler radar data. We also acknowledge Carl Friehe and Shawn Burns of theUniversity of California, Irvine, for their assistance in determining biases in the P-3 in situ data. The NCAR Zebra software was used to construct the satellite photo and flight track plots in Fig. 1. This work was supported by NSF Grant 9215507 and NOAA/OGP Grant 8R1DA110. We lastly acknowledge the many stimulating discussions about the nature of squall lines, their structure, and momentum flux characteristics as well as the use and interpretation of airborne Doppler radar data with Peter Hildebrand (NCAR), Robert Houze (University of Washington), Dave Parsons (NCAR), Frank Roux (Laboratoire d’Aerologie, Toulouse, France), Bradley Smull (NOAA/NSSL), Wei-Kuo Tao (NASA/GSFC), Jacques Testud (CRPE/France), Morris Weisman (NCAR), and Edward Zipser (Texas A&M University).
