Subject: | TWP/SONDE/C1 - Bad RH sensors |
DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 12km). The RH oscillates rapidly in a 20% range and the oscillation seems to stop when the temperature is below ~45 degC. These are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

Subject: | TWP/SONDE/C1 - Bad RH at beginning of sounding |
DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~15 %RH) and not so low (~50 %RH) and the oscillation seems to stop when the temperature is below ~40 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~0 %RH) and not so low (~80 %RH) and the oscillation seems to stop when the temperature is below ~40 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

Subject: | TWP/SONDE/C1 - Bad RH in short interval aloft |
DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit on this sonde failed about 31 minutes into the flight. The RH values look reasonable from the surface to approximately 8.25 km at which point they begin to oscillate between 0 and 40%. This behavior stops when the sonde reaches approximately 11.0km when the air temperature drops below -40 degC. The oscillation stops at that point, though the RH remains higher than might be expected even under supersaturated conditions. |

DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~2 %RH) and not so low (~90 %RH) and the oscillation seems to stop when the temperature is below ~40 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~1 %RH) and high (~80 %RH). According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

DataStreams: | twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 0km and 11km). The RH oscillates rapidly between low (~5 %RH) and not so low (~70 %RH) and the oscillation seems to stop when the temperature is below ~40 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |
