Subject: | TWP/Sonde/C1 - Bad RH Values |
DataStreams: | twpsondewnpnC1.a1, twpsondewnpnC1.b1 |
Description: | The RH values from the surface to approximately 11.5 km oscillate between reasonable values and zero. This is apparently caused by a failure in the RH sensor heating process. Although the oscillation stops when the heating stops (at temperatures below ~ -45degC) I think the values must be viewed as suspect. |

DataStreams: | twpsondewnpnC2.a1, twpsondewnpnC2.b1 |
Description: | The RH sensor heating circuit failed on this sonde. This results in oscillation of reported RH between reasonable values and values near zero. This was an AIRS validation sounding. |

Subject: | TWP/SONDE/C1 - Questionable RH |
DataStreams: | twpsondewnpnC1.a1, twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between 5km and 10km). The RH oscillates rapidly between low (~5 %RH) and not so low (~50 %RH) and the oscillation seems to stop when the temperature is below ~35 degC. According to Vaisala these are symptoms of failure in the ASIC (application specific integrated circuit) that controls the heating. |

Description: | The RH sensor heating circuit failed on this radiosonde. The RH-related values obtained between 0 and 10000 meters oscillate between near-zero and reasonable ambient values. Above 10000 the RH values are likely correct. |

DataStreams: | twpsondewnpnC1.a1, twpsondewnpnC1.b1 |
Description: | It appears that the RH sensor heating circuit failed during this portion of the sounding (approximately between the surface and 11km). The RH oscillates rapidly between low (~0 %RH) and high (~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/C2 - Failure of RH sensor |
DataStreams: | twpsondewnpnC2.b1 |
Description: | The RH sensor ASIC that controls the sensor heating failed. As a result the RH at the beginning of the sounding oscillates between near-zero and ambient values. The RH heating cycle stops when the ambient temperature reaches below -30 degC; above this level RH values should be valid. |
