Subject: | SGP/MET/E9 - Time-stamp uncertainty |
DataStreams: | sgpmetE9.b1 |
Description: | 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. |

Subject: | SGP/MET/E9 - RH probe failure |
DataStreams: | sgpmetE9.b1 |
Description: | 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. |

Subject: | SGP/MET/E9 - False tips in high winds |
DataStreams: | sgpmetE9.b1 |
Description: | The TBRG's were mounted at a height that made them prone to vibrations caused by high winds which may have caused false tips. The end date of this DQR indicates when the rain gauge was lowered to mitigate these effects. Effects on the total precipitation amounts are assumed to be negligible. |
