SGP/EBBR/E12 - Wind Direction Malfunction

For the period indicated, a malfunction in the E12 EBBR wind direction
sensor caused the following data values to be incorrect:

5 minute: res_ws, wind_d, and sigma_wd
15 minute: mv_wind_d
30 minute: res_ws, wind_d, and sigma_wd.

Wind direction normally indicated smaller or larger than it should have.
The affected time period was determined from comparison with data from E7,
Elk Falls EBBR, which is located north of E12.

The wind direction sensor (S/N 3034) was replaced with S/N 3039 at 1822 GMT
on June 7, 1995.

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