SGP/EBBR/E9 - Wind Direction Sensor Malfunction

During numerous intermittent times during the period listed, the wind direction
sensor at E9, Ashton, KS malfunctioned, putting out a value of 135.  The
sensor was replaced on 30 September 1997, at 1550 GMT.  All wind direction data
with values of 135 during the period listed should be considered incorrect.
The affected data are:

 5 minute: res_ws, wind_d, sigma_d

15 minute: mv_wind_d

30 minute: res_ws, wind_d, sigma_d

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