We are extremely grateful to the IFREMER Centre ERS d’Archivage et de Traitement (CERSAT) for producing and distributing ECMWF/IFR and IFR2 data. Dr. Frank Wentz (Remote Sensing Systems) kindly provided SSMI winds for July 1995. The manuscript benefited greatly from constructive comments by Dr. Craig Lee (WHOI), Dr. Ad Stoffelen (KNMI), and two anonymous reviewers. Data processing and graphics were made by Peter Woiceshyn (JPL) in his usual proficient manner. The work described in this paper was supported by NASA 622-47-09 (DH), NASA SeaWinds Project 229-18-41 (DH), NASA NSCAT Project via JPL Contract 959351 (MHF), and ONR Grant N00014-94-1-0161 (RW). The research described in this paper was performed, in part, by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
