Subject: | PYE/MET/M1 - Wind Speed data contain offset due to induced voltage |
DataStreams: | pyemetM1.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. |

Subject: | NIM/MET/M1 - Wind Speed data contain offset due to induced voltage |
DataStreams: | nimmetM1.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. |

Subject: | NIM/MET/M1 - PWD cumulative precipitation incorrect |
DataStreams: | nimmetM1.b1 |
Description: | The Present Weather Detector is a serial sensor. The MET system datalogger reads in the data from this sensor. During the time in question serial comms problems were causing the data from the sensor to be read incorrectly. The data for one variable showed up in data for another variable or not at all. We reprocessed the data to correct as much of this error as we could. The cumulative rainfall variable was calculated from the instantaneous rainfall variable during reprocessing. Since we cannot be entirely sure all cumulative rainfall values are correct or were completely captured the cumulative rainfall data is considered to be unreliable. This issue shows up when comparing the cumulative rainfall data at the end of the day 07/31/2006 (79.08) and the beginning of the next day 08/01/2006 (3.17). Clearly we were either under or over-estimating the cumulative rainfall. |

Description: | On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |

Subject: | SGP/MET/STAMP/All - Freezing Rain Event |
DataStreams: | sgpmetE15.b1, sgpmetE40.b1, sgpmetE31.b1, sgpmetE38.b1, sgpmetE34.b1, sgpmetE36.b1, sgpmetE21.b1, sgpmetE32.b1, sgpmetE39.b1, sgpmetE37.b1, sgpmetE33.b1, sgpmetE11.b1, sgpmetE35.b1 |
Description: | A freezing rain event potentially affected some of the STAMP and MET tipping bucket rain gauges. The rain accumulation amounts generally agree (2 exceptions noted below) but the timing and rate of precipitation may disagree at times between the STAMP and MET. Instruments at E33 and E39 were found to differ more than the expected uncertainty and will be covered in additional DQRs if a problem is found. |

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. |
