Subject: | SGP/MET/E13 - Temperature/humidity sensor occasionally failed 6-month field calibration checks |
---|---|
Affected Datastreams: | sgpmetE13.b1 |
Description | The temperature/humidity sensor was not calibrated annually during this time. The temperature/humidity readings failed the 6-month field calibration check on four occasions during this period (temperature reading low, humidity reading high). Upon removal, the field calibration check reported the humidity reading was high (+4%). In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. A detailed summary is available in the ARM technical report: https://www.arm.gov/publications/tech_reports/doe-sc-arm-tr-192.pdf |

---|---|
Affected Datastreams: | sgpmetE13.b1 |
Description | The TBRG's were mounted at a height that made them prone to vibrations caused by high winds which may have caused false tips. The end date of this DQR indicates when the rain gauge was lowered to mitigate these effects. Effects on the total precipitation amounts are assumed to be negligible. |

Subject: | SGP/MET/STAMP/All - Freezing Rain Event |
---|---|
Affected Datastreams: | sgpmetE38.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. |

---|---|
Affected Datastreams: | sgpirt200msE13.a1 |
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. |
