Subject:	NSA/XSAPR/C1 - Reprocessing Notice (RID 1318)
DataStreams:	nsaxsaprvptC1.a1, nsaxsaprrhiC1.a1
Description:	See below for details of reprocessing that was completed on 20151207. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- The time variable in the a1 datastream contains incorrect times for sweeps in which one or more rays were not collected by the instrument. Data in field variables contains a default value and not _FillValue for gates in rays which have fewer than the maximum number of gates collected by the instrument for that volume. This has been observed in RHI scans in the NSA and SGP where the instruments does not collect gates which would have a height above a instrument defined altitude. These gates should be masked and indicated by _FillValue. The value in these gates is unusual for the field and typically easy to identify as incorrect.

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.
