SGP/EBBR/E4 - Instrument problem

Wind direction was flat lining near zero and incorrect.

Use wind direction data from the co-located SMOS system.

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

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

• Wind direction vector mean (mV)(wdir_vec_mean_mv)
