Subject: | TWP/MWR/C1 - Radiometer failure |
DataStreams: | twpmwrC1.00, twpmwrlosC1.b1, twpmwrtipC1.a1 |

Subject: | TWP/SONDE/C2 - Surface Temperature Incorrect |
DataStreams: | twpsondewnpnC2.b1 |
Description: | The first two temperature values in the datafile are incorrect. It appears that the observer mis-typed the surface temperature as -27 instead of +27. The next value was 8 which is also incorrect and was caused by the system interpolating from the incorrect surface value and what the sonde temperature sensor was reading. |

Subject: | TWP/SONDE/C2 - Surface RH value incorrect |
DataStreams: | twpsondewnpnC2.b1 |
Description: | The surface RH value was incorrect. It appears the observer mis-typed 70 instead of 80. This error also caused the dew point temperature to be incorrect. |

Subject: | TWP/SONDE/C2 - Surface RH value incorrect |
DataStreams: | twpsondewnpnC2.b1 |
Description: | The surface RH was reproted as 78%. The value should have been in the low 50's. It appears the observer did not allow the sonde to equilibrate to ambient conditions before taking the reading. This error also caused an incorrect dew point. |

DataStreams: | twpsondewnpnC1.b1 |
Description: | The surface RH value of 77% when the value should have been in the low 60's. It appears the observers did not allow the sonde to equilibrate to ambient conditions before collecting the surface data. This error also caused the dew point to be incorrect. |

Subject: | TWP/SONDE/C2 - Surface RH Value incorrect |
DataStreams: | twpsondewnpnC2.b1 |
Description: | The surface value entered by the observers for RH (96%) is incorrect. At the ascent time listed in the .ptu file the readings by the Sonde were around 65%. This low RH value is supported by the nearby SMET tower RH reading of 71.8%. This also caused the surface dew point to be incorrect. |

DataStreams: | twpsondewnpnC2.b1 |
Description: | The surface Rh was entered as 94%. The ascent time has 72% and this value is supported by RH values from the nearby SMET system. This error also will affect the dew point. |

DataStreams: | twpsmet60sC2.b1 |
Description: | Lower wind speed sensor had degraded bearings. This sensor was reporting as much as 0.4 m/s lower values than the upper sensors when the winds were 2 m/s or below. The sensor was replaced. |
