The AOC flight crew helped to collect the radar and flight-level data, and the AOC scientific staff processed the flight-level data. Several folks in HRD helped process the radar data: Mike Black edited the vertical incidence data, shared insights into vertical velocities in hurricanes and generated two figures of vertical velocity for this paper; Nancy Griffin merged the Doppler and reflectivity tapes for PDD analysis; and Paul Leighton and Joe Griffin modified the PDD interpolation software to deal with some of the idiosyncrasies of the Gilbert Doppler dataset. John Gamache developed the variational software and assisted us in applying it to the interpolated Doppler velocities to synthesize the windfields. Wen-Chau Lee and Susan Stringer of the Atmospheric Technology Division of the National Center for Atmospheric Research provided the software (Grid2PS) that produced several figures from the radar data. Comments on an earlier draft by Mike Black and Chris Samsury led to substantial improvements in the paper. Constructive comments from three anonymous reviewers helped us clarify several points in the final version.
