NSA/METOWER - Reprocess: Incorrect NSA wind direction minima and maxima

From the time of installation of the NSA C1 Met-tower system on 24 MAR 1998
until 29 NOV 1999 all wind direction minima and maxima were reported as raw
(unrotated) data.  In order to obtain correct minima and maxima 30 deg must
be subtracted from the value.  All mean wind directions were computed from
rotated (corrected) data.
