--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------


The SGP.C1 915RWP was operated in a non-standard mode during the Nocturnal
Flux IOP (approximately the month of September). The profiler was placed into a constant 
high temporal and spatial resolution mode rather than alternating between modes as it does 
routinely. 30 min averages were produced (usually 60 min) at a 60 m gate resolution for 
both winds and RASS. 

Data were processed and archived, but the processing algorithm interpreted this data as 2 
different power levels per hourly sample rather than 30 minute samples at the same power 
level.  Data will be reprocessed.

were reseated 5/18.

scrutinize data during this time period. Sensor replacement appears to have corrected the 
problem.

SGP Site Power Outage Due to Winter Storm

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.
