Subject: | TWP/C1 - Incorrect elevation reported in Manus Data |
DataStreams: | twpsondewnpnC1.a1 |
Description: | (From Bill Clements) We have been using 6m MSL as the station elevation of Momote (Manus). This was based on information posted near the station barometer in the Momote Weather Service Office. It turns out that the official WMO station elevation for Momote is 4m MSL and the upper air elevation is 5m MSL. All Manus instruments except the sonde station are at 4m MSL. The sonde launching station is at 5m MSL. |

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. |

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. |

Subject: | TWP/SONDE/C1 - Bad RH |
DataStreams: | twpsondewnpnC1.a1, twpsondewnpnC1.b1 |
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. |

Subject: | TWP/SONDE/C1 - Bad RH sensor |
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. |
