SGP/EBBR/E2 - EBBR E2 Wind Direction Sensors Frozen

Wind direction sensors were frozen stalled during this period.
Wind direction from 0630 through 1100 GMT.  Data values that 
were affected were:

 5 minute: sigma_wd, wind_d
15 minute: mv_wind_d
30 minute: sigma_wd, wind_d

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

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

• Wind direction vector mean (mV)(wdir_vec_mean_mv)
