Notes
-----

1.  Wind speed and direction are calculated from position change
    informaton and are and stored in the database.  The user can
    optionally select u & v wind components and those will be
    calculated and returned.  The QC results from speed and direction
    will be used in either case, and if one of the map projections has
    been selected via the MSETDOM call, the winds will be rotated to
    match the projection.

2.  The only quality control currently performed on the observed pressure, 
    air temperature, and relative humidity is to subjectively flag them as
    bad, pending further work to determine the usefulness of these
    observations.

3.  The cutdown flag is used to command the balloon to self-destruct.

       Value      Meaning
       -----      -------
         0        Cutdown not asserted
         1        Cutdown asserted

* The WISDOM Balloon Wind data is only available with the FSL database.
