SGP/EBBR/E20 - Wind Direction Stuck at 100 Degrees

The wind direction sensor was stuck at about 100 degrees.  This did
not affect the primary measurements (net radiation, soil heat flow, sensible heat flux, 
latent heat flux).

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

• Wind direction vector mean (mV)(wdir_vec_mean_mv)

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