DataStreams:sgpaospsap3wC1.b1
Description:
See below for details of reprocessing that was completed on 20140717.  Original DQR

A typo was found in the PSAP flow calibration. The measured offset was -0.0325 and the 
typo was -0.325. The RAW data have been corrected but the b1 level data has not. b1 level 
data will be reprocessed.

SGP Site Power Outage Due to Winter Storm
DataStreams:sgpaospsap3wC1.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.
