Subject: | TWP/SONDE/C2 - Bad RH sensor |
DataStreams: | twpsondewnpnC2.b1 |
Description: | It appears that the RH sensor heating circuit failed during this sounding. The RH oscillates rapidly between low (~0 %RH) and not so low (ambient %RH) and the oscillation seems to stop when the temperature is below -50 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

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. |

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. |

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. |

Subject: | TWP/SONDE/C2 - Wind data missing |
DataStreams: | twpsondewnpnC2.b1 |
Description: | A GPS problem associated with Vaisala BBSS ground station software issues caused the ground stations to enter into an error state when using GPS wind finding. In some instances, the flight was aborted due to the error state and not data was collected. A workaround was developed to allow sondes to be launched without collecting wind data. |
