Subject: | SGP/THWAPS/B4 - RH sensor failure |
DataStreams: | sgpthwapsB4.b1 |
Description: | RH values dropped to ~20% below those recorded at nearby sites and occasionally flatlined at 0%. RH sensor was replaced. |

Subject: | SGP/THWAPS/C1 - Barometer intermittent |
DataStreams: | sgpthwapsC1.b1 |
Description: | Intermittent dropouts on the barometer data were occurring, with data reading low or missing. Loose wiring was the probable culprit. In most instances, only 1 minute of data was missing. Linear interpolation between the last known good point and the first good point following the dropout can be accomplished. |

Subject: | SGP/THWAPS/C1 - Time stamp of data record incorrect |
DataStreams: | sgpthwapsC1.b1 |
Description: | Due to problems with the collector system, the datalogger was being time synched inappropriately. This problem was intermittent and did not affect every time stamp. The worst case time adjustments were approximately +/- 7 minutes. These were infrequent and most of the time adjustments were less than 7 minutes. |

Subject: | SGP/THWAPS/C1 - Wind speed incorrect |
DataStreams: | sgpthwapsC1.b1 |
Description: | The wind sensor was reporting 0 m/s winds for excessive periods of time and appeared to measure lower wind speeds than nearby co-located wind sensors. Sensor was replaced. |
