SGP/MET/E9 - Wind Speed Data Incorrect

Wind speed sensor reference wire became detached.  This caused all wind sensor data to 
report near 0 m/s.

• Wind speed vector mean(wspd_vec_mean)
• qc_wspd_vec_mean
• qc_wspd_arith_mean
• Wind speed, lower, 1-min avg(wspd_arith_mean)

SGP/MET/E9 - Time-stamp uncertainty

Between 20100503 and 20100507 the sgp.E9 instruments (EBBR, MET, SIRS, SWATS) time clocks 
were drifting outside the allowable +/-3 seconds.  During the specified period, the 
swings ranged from -326 to +637 seconds.

• Humidity, relative, at 2-m height, 1-min avg(rh_mean)
• qc_temp_mean
• qc_wdir_vec_mean
• Wind speed vector mean(wspd_vec_mean)
• qc_wdir_vec_std
• Wind direction, vector, lower, 1-min avg(wdir_vec_mean)
• Barometric Pressure(atmos_pressure)
• qc_rh_mean
• qc_wspd_vec_mean

• Corrected total precipitation measured by TBRG(tbrg_precip_total_corr)

SGP/MET/E9 - RH probe failure

The T/RH probe failed. The resulting problem led to very unreasonable values of RH (~160%) 
which caused the vapor pressure values to also be incorrect.
