Subject: SGP Site Power Outage Due to Winter Storm
Affected Datastreams: sgpnoaaaosccn100C1.b1
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/E13 - False tips in high winds
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.

  • tbrg_precip_total (TBRG precipitation total)
