Subject: | SGP/SONDE/C1 - Broken temperature sensors |
DataStreams: | sgpsondewnpnC1.a1, sgpsondewnpnC1.b1 |
Description: | The temperature sensors broke at launch on both of these soundings. All of the temperature-related data (tdry, rh, dp) are incorrect. |

Subject: | PYE/SONDE/M1 - Broken RH sensor |
DataStreams: | pyesondewnpnM1.b1 |
Description: | One of the RH sensors on this radiosonde was bad. The RH oscillates rapidly between near 0 and ambient up to approximately 11 km. The near-zero values are incorrect. |

Subject: | PYE/SONDE/M1 - Bad temperature and RH |
DataStreams: | pyesondewnpnM1.b1 |
Description: | The temperature appears to be approximately 10 degC too high during the entire sounding. This also causes the RH to be too low. Most likely the problem was a bad temperature sensor. |

Subject: | PYE/SONDE/M1 - Bad RH sensor |
DataStreams: | pyesondewnpnM1.b1 |
Description: | The RH sensor heating circuit failed on this sounding. RH values during the first part of the sounding oscillate between a reasonable value and a very low value. It appears that (a) the heating was out of phase, and (b) incorrect values were being reported during the first 10 minutes or so of flight. |

Subject: | PYE/SONDE/M1 - Bad RH sensor |
DataStreams: | pyesondewnpnM1.b1 |
Description: | Two problems here - failure of the RH sensor heating circuit and a bad RH sensor. |

Subject: | SGP/SONDE/C1 - Increased precision for alt, dp, pres, rh, tdry |
DataStreams: | sgpsondewnpnC1.b1 |
Description: | The output precision of the following variables was increased 20060928 alt changed from 1m to 0.1m dp changed from 0.1degC to 0.01degC pres changed from 0.1 hPa to 0.01 hPa RH changed from 1%RH to 0.01%RH tdry changed from .1degC to 0.01degC Note that the increase in precision does not necessarily imply an increase in accuracy. Users are cautioned to continue to use their best scientific judgement when using these or any other data. |
