Subject: | TWP/Sonde/C1 - Bad RH Values |
DataStreams: | twpsondewnpnC1.b1, twpsondewnpnC1.a1 |
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.b1, twpsondewnpnC1.a1 |
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/C2 - Strange problem with data - |
DataStreams: | twpsondewnpnC2.b1 |
Description: | This is very strange. The data has what appears to be a pressure jump at launch (from 1007.2 to 956.5 hPa) but the sounding temperature and RH data clearly look to be interpolated between the surface and tropopause. By examining the absolutely raw data, I found that the system assigned an elapsed time of 408 seconds (since system start up) to the launch point, but there is no raw data between 410 and 532 seconds. The raw pressure value at 410 seconds is 1007.6 hPa and that at 532 seconds is 40.9 hPa! Unless this sounding was done by using a rocket-powered balloon (maybe even then), it would be impossible for the sonde to get to 40.9 hPa in 2 minutes. Because the apparent gap is only two minutes, the system was able to interpolate but is not sophisticated enough to understand that the limits of the interpolation are unreasonable. I can't imagine what went wrong - I've not seen anything like this before. |

The RH values look reasonable, though somewhat noisy, from the surface to approximately 6.9 km (439 hPa) at which point they begin to oscillate between 0 and 100 %. This behavior stops when the sonde reaches approximately 11.5km (232 hPa) 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. |

Subject: | TWP/SONDE/C2 - Operator used wrong calibration tape |
DataStreams: | twpsondewnpnC2.b1 |
Description: | It appears as though the opperator used the wrong calibration tape for this sounding. The primary symptom is a jump in temperature from a surface value of 30.1 degC to the first value aloft of 61.0 degC. Secondly, the recorded serial number for this sounding is Z1430179 which is the same serial number recorded for the previous sounding. This problem points to three failures of procedure (I have notified TWP site ops by e-mail). The first failure is using the wrong tape. The second failure is not checking the radiosonde values before launch which relates to the third failure of not entering the radiosonde values as the surface values of the sounding. |
