Subject: | PYE/MPL/M1 - wrong temperature calibration |
DataStreams: | pyemplM1.a1 |
Description: | Wrong calibration coefficients were applied to the temperature values. These are engineering housekeeping data only. The scientifically relevant measurements were unaffected. |

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/MWRP/M1 - Bias in Ground Relative Humidity Measurement |
DataStreams: | pyemwrpM1.00, pyemwrpM1.b1 |
Description: | On June 17 2005, the MWRP was re-installed at PYE after the Super Blower was replaced by the old style dew blower. The relative humidity ground sensor in the dew blower is not as accurate. This resulted in a negative relative humidity bias of about 5.9 %. In other words the MWRP sensor was underestimating the relative humidity. The bias was determined by comparing MWRP measurements with SMET and radiosonde measurements. The MP.cfg file for the MWRP was changed to reflect this bias on 09/02/2005 and will take effect on 09/03/2005 0000 GMT |

Subject: | PYE/MPL/M1 - Erroneous temperatures |
DataStreams: | pyemplM1.a1 |
Description: | The temperature readings for the laser, detector, and instrument are erroneous. Incorrect calibration factors; data should not be used. This time period is prior to the official start of the PYE deployment. |

Subject: | PYE/AOS/M1 - Data processing problem |
DataStreams: | pyeaosM1.a1, pyenoaaaosM1.b1, pyenoaaaosavgM1.b1 |
Description: | The AOS data was reprocessed for the AMF, SGP and NSA sites. There was an error in the processing of the corrections for the PSAP absorption signal such that a low pass filter was implemented for the scattering data used in these corrections.The difference between the corrected and previous data is < 0.05 Mm-1 (below the instrument detection limit) and should not have a significant effect on the previous data. Data will be reprocessed at a later time when more significant changes to the data processing are implemented. |
