Subject: | TWP/SMET/C3 - Upper Wind Sensor Data Questionable |
DataStreams: | twpsmet60sC3.b1 |
Description: | The wind_up vs. wind_low wind directions diverged, with the differences between the two eventually reached 45 degrees. The Upper sensor was found to be mis-aligned and loose. |

Subject: | TWP/SMET/C3 - Lower Wind Direction Intermittently Wrong |
DataStreams: | twpsmet60sC3.b1 |
Description: | The lower wind sensor cabling had a problem causing an intermittent connection for the wind direction data. |

Subject: | TWP/SMET/C2 - ORG rainfall measurements too large |
DataStreams: | twpsmet60sC2.b1 |
Description: | The ORG was collecting large amounts of rainfall compared to the co-located tipping bucket raingauge. The cable was chewed by mice causing the wires to make contact intermittently mimicking rainfall. |

Subject: | TWP/SMET/C1 - ORG Precip Data Incorrect |
DataStreams: | twpsmet60sC1.b1 |
Description: | Moisture intrusion into the sensor body allowed condensation on the lens of the ORG. Continual and long-term precipitation was reported during this time. |

Subject: | TWP/SMET/C3 - Upper wind speed data incorrect |
DataStreams: | twpsmet60sC3.b1 |
Description: | Beginning on 07/08, the upper wind sensor started reporting significantly lower wind speeds than the lower wind sensor. The cable connections weather proofing failed allowing corrosion to occur and increasing he resistance of the cables. This in turn lowered the wind speeds artificially. |
