Subject: | PYE/AERI/M1 - Incorrect reporting of the hatch open status |
DataStreams: | pyeaerisummaryM1.b1 |
Description: | The polarity of the hatch controller was incorrect. The hatch was reported in an indeterminate position (red) when the controller was open and collecting data. Normally, when the hatch open metadata flag is red, the hatch is closed or partially closed and there is no sky data. However, because the polarity was reversed, the hatch flagged red when the hatch was open. The problem was resolved by reversing the polarity through software. The hatch flag now correctly reports the status of the hatch. |

Description: | The lower half of the TSI images were blurry due to water in the camera lens and/or filter. The problem was corrected when both were cleaned. |

Subject: | PYE/ECOR/M1 - Reprocessed: Wind direction offset corrected |
DataStreams: | pye30ecorM1.b1 |
Description: | The SMET wind direction was consistently 15 to 20 degrees larger than the wind direction determined by the ECOR. The ECOR was mistakenly aligned to magnetic north during this period. The magnetic declination is 14 deg. 58 min., which explains most of the difference. The ECOR data for this period were reprocessed in November 2006 to add 15 degrees to the wind direction. No other changes were made to the data. The reprocessed data were archived in January 2007. |

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/ECOR/M1 - Flux Data Suspect For Some Wind Directions |
DataStreams: | pye30ecorM1.b1 |
Description: | For some wind directions the horizontal fetch was not representative of the field in which the AMF was located. Therefore, for the wind direction ranges 66-92 (buildings and trees) degrees, the fluxes are affected by insufficient fetch and surfaces, buildings, or vegetation that are not similar to the local field conditions. |
