An incorrect offset of 7 degrees was added to the wind direction to
correct for misalignment of the towers to true north. The wind direction data may be
corrected but the vector averaged wind speed cannot. Subsequent audits have highlighted
problems with past measurements of tower alignments. All corrections to wind direction are
being removed and Users are directed to view the Instrument Handbook for a table listing
all tower alignment deviations from true north. Users can adjust the data at their
discretion. |
