Subject: | PYE/NFOV/M1 - Intermittent missing data |
DataStreams: | pyenfov2chM1.00, pyenfov2chM1.b1 |
Description: | During the Pt Reyes deployment of the NFOV, the instrument experienced intermittent data gaps due to communications problems. Data gaps occurred for the following date ranges: 20050718-20050723 20050727-20050730 20050803-20050804 20050813-20050816 20050820-20050822 20050826-20050827 20050830-20050902 20050908-20050910 |

Subject: | PYE/NFOV/M1 - Intermittent data gaps |
DataStreams: | pyenfov2chM1.00, pyenfov2chM1.b1 |
Description: | Intermittent data collection of the NFOV. Data collection not successful regularly during day light hours but generally caught up during the nighttime hours. Occasionally the system stopped collecting altogether and a reboot of the network components was required to restart collection. Data gaps are largest 18 through 23 of July and 27 through 30 July. |

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. |
