SGP/EBBR/E22  - Wind Direction Frozen Stopped By Ice

The wind direction sensor was frozen stopped by ice from a storm.  
The wind direction, sigma_wd, and residual wind speed measurements 
are incorrect.

• Wind direction vector mean (mV)(wdir_vec_mean_mv)

• Wind speed vector mean(wspd_vec_mean)
• Wind direction vector mean(wdir_vec_mean)
• Wind direction vector mean standard deviation(wdir_vec_std)

• Wind direction vector mean standard deviation(wdir_vec_std)
• Wind speed vector mean(wspd_vec_mean)
• Wind direction vector mean(wdir_vec_mean)
