The high winds today provide an opportunity to adjust the wind directions on the profiles towers. We only measured the 3m sonic azimuth with the DataScope and assumed that the other sonics on the profile towers were aligned with the lowest level. For the past 6 hours, the wind speed above 3m at near has been higher than 15 m/s, while that at 3m has been 13-14 m/s. The following table shows the median wind directions relative to that at the lowest level. These values should be subtracted from the azimuth at each level.

The period used is 2013 10/9 08:00 - 16:00. See accompanying plots for the exact period selected for high wind speeds.
