SGP EBBR E18 - E18 EBBR Wind Direction Frozen

The wind direction sensor was frozen stopped.  The indicated measurements are incorrect as 
a result.

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

• Wind direction vector mean (mV)(wdir_vec_mean_mv)

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