Description: | The 2m data for temp, RH, dew point, wind speed wind direction & vapor pressure were incorrect. The voltage values for the datalogger at that level were reporting as 60V with excursions to 100V. These values should have damaged the logger at that level. After an extended power outage on 08/04 the data all became reasonable. There is no explanation as to the cause of this failure. |

Subject: | HFE/MET/M1 - Wind speed data contain offset due to induced voltage |
DataStreams: | hfemetM1.b1 |
Description: | The marine model of the RM Young wind sensor needs twisted pair shielded cable. The manufacturer did not originally supply the pigtail with twisted pair shielded cable. Use of twisted pair shielded cable for the rest of the cable run to the logger was also not specified. This caused an induced voltage in the wind speed line from the wind direction excitation. The induced voltage varied from sensor to sensor and probably changed anytime the cable was replaced or parts of the wind sensor were repaired or replaced. The induced voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s. |

Description: | The cable for the wind monitor is not a twisted pair shielded cable. This caused an induced voltage on the wind sensor wires from the wind direction measurement excitation voltage. A small offset is added into the wind speeds. This value varies. Most frequently the values of 0.49, 0.588 and 0.686 m/s were added into the wind speed. On 11/27/2008 the value jumped to 0.98 m/s for most of the day. |

Description: | Starting 14:17 GMT on 12/4/2011 the CMH Dew Point began reporting missing value, CMH relative humidity was flat-lining at 100% and CMH saturated vapor pressure was flat-lined at a high value. This condition continued very intermittently for several months. Issue was frosting and a failed ventilation fan. |

DataStreams: | grwmergesonde1maceM1.c1 |
Description: | See below for details of reprocessing that was completed on 20150209. Original DQR category: 3 (Yellow, Suspect). ----------------------------------------------------------- MERGESONDE sometimes uses bad or questionable precipitable water vapor data to scale the relative humidity profiles provided by the rh_scaled field. In addition, this bad input data is not properly indicated by the vapor_source or qc_rh_scaled fields. This problem appears to typically occur when there is moisture impacting the microwave radiometer causing large spikes in brightness temperatures. During these periods the rh_scaled values are often saturated at 101% for much of the profile. A new version of the MERGESONDE VAP has corrected this problem, and these data will eventually be corrected by a reprocessing task. |

Subject: | NSA/MET/C1 - Present weather detector hardware error |
DataStreams: | nsametC1.b1 |
Description: | The present weather detector began reporting a hardware error (a bad connection of the rain sensor). The problem began intermittently, and then became constant after 2/8. Visibility data are not affected, except when the instrument was disconnected for maintenance (2/24 and 3/1, indicated by DQ values). |

Subject: | SGP/MET/E9 - Temperature occasionally failed 6-month field calibration checks |
DataStreams: | sgpmetE9.b1 |
Description: | The temperature/humidity sensor was not calibrated annually during this time. The temperature reading failed the 6-month field calibration check four times during this period. Upon removal, the field calibration check reported the temperature sensor may have been reading high (< 1 deg C). In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. |

Subject: | SGP/MET/E11 - Temperature/humidity sensor failed a field calibration check |
DataStreams: | sgpmetE11.b1 |
Description: | The temperature/humidity sensor was not calibrated annually during this time. The temperature failed a field calibration check on 10/10/2007 (read high), but passed subsequent checks until replacement on 4/7/2009. In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. |

DataStreams: | sgpmetE15.b1 |
Description: | The temperature/humidity sensor was not calibrated annually during this time. The temperature/humidity readings failed the 6-month field calibration check two times during this period (temperature read low, humidity read high). In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. |

Subject: | SGP/MET/E37 - Temperature/humidity sensor not calibrated annually |
DataStreams: | sgpmetE37.b1 |
Description: | The temperature/humidity sensor was not calibrated annually during this time, but passed all 6-month field calibration checks. Comparison with a nearby Mesonet site suggests the relative humidity may be reading low, especially in high humidity situations. An exit calibration will characterize severity when the sensor is replaced. In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. |
