Subject:	SGP Site Power Outage Due to Winter Storm
DataStreams:	sgpaosacsmC1.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/AOS/C1 - Wildfire smoke plumes advecting over facility
DataStreams:	sgpaosacsmC1.b1
Description:	Smoke from nearby wildfires advected through SGP C1 during the listed affected time ranges, resulting in high signals observable in many of the listed AOS datastreams.

Subject:	SGP/ACSM/C1 - Filter switching valve not operating
DataStreams:	sgpaosacsmC1.b1
Description:	Filter switching valve was not operating because of a faulty circuit board. Problem was fixed and data have been collected from the end of the specified time period.

Subject:	SGP/ACSM/C1 - Low inlet pressure in sample position
DataStreams:	sgpaosacsmC1.b1
Description:	The data are suspect because the new filter switching valve was out of adjustment causing low inlet pressure in the sample position. The problem was corrected by the onsite operator.
