Description: | Power outages apparently led to the THWAPS HMP233 temperature and RH sensor being replaced at C1. The power went out at 0340 on 3/9 was restored at 0635 and went out again at 2025. The new HMP233 appears to be incorrectly calibrated and all temperature data since its installation are wrong. If I am correct about the nature of the calibration problem, the true average temperature can be recovered from that recorded by a linear conversion, but I don't think its worth the trouble. |

Subject: | SGP/TWR/C1 - Southeast Side RH Too Large |
DataStreams: | sgp1twr10xC1.b1, sgp30twr10xC1.b1 |
Description: | The T/RH probes installed on the 25 m and 60 m levels of the southeast side of the tower on 8/15/03 gave RH readings that were too large for RH above 65%. The difference between the west and southeast side RH was within the combined accuracies of the sensors up to about 80% RH. Above 80% RH the southeast side RH was much larger, with the difference increasing to 10% larger (or more) at 100% RH. The vapor pressure from the southeast side (calculated with RH) was also too large. The probes were replaced on 2/10/04 and the two sides of the tower now agree fairly well, with RH not exceeding 100% during saturation. |

Subject: | SGP/THWAPS/C1 - Minor bias in humidity |
DataStreams: | sgpthwapsC1.a1, sgpthwapsC1.b1 |
Description: | The THWAPS humidity sensor output was scaled so that the instrument output voltage range (0-1VDC) represented 0-100 %RH. Comparisons with the co-located chilled mirror sensor at the CF suggested that the THWAPS RH sensor was reading artifically low at high humidities because of this 100 %RH maximum. The scaling of the system was changed so that 0-1 VDC now represents 0-110 %RH. This resulted in a slight loss of precision in the measurements, but since the RH measurement is only accurate to 2-3 %RH at best, this isn't a significant problem. |

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. |

DataStreams: | sgporgC1.b1 |
Description: | False positive observations occur during foggy periods and the accompanying rain gauges should always be consulted. However, the period covered by this DQR was not foggy and false positive readings became an issue. The instrument was removed for repair in 10/1/2009. |

DataStreams: | sgp1twr10xC1.a1, sgp1twr10xC1.b1, sgp30twr10xC1.a1, sgp30twr10xC1.b1 |
Description: | The RH and therefore vapor pressure measurements on the 25 meter level, southeast side of the 60 m tower (data from CR10X) were incorrect because the relative humidity portion of the T/RH probe malfunctioned. It is unknown at what day and time the failure occurred (it should be obvious from the data), although it was in the middle of the Fall combined IOP; I was not receiving the data at the time. The T/RH probe was replaced on 26 September. |

DataStreams: | sgp1twr10xC1.b1, sgp30twr10xC1.b1 |
Description: | 60m temperature data for the southeast side of the tower was incorrect during the period because of a poor connection at the carriage data connector. The poor connection caused resistance to be too large as seen by the PRTD sensor in the T/RH probe, resulting in temperatures that were 2 to 6 degrees too large. The problem ended when the carriage was lowered, then raised, reestablishing a good connection. |
