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