SGP/ARSCL/C1 - ARSCL Cloud Bases and Low-level reflectivities
DataStreams:sgparsclbnd1clothC1.c1
Description:
Prior to February 4, 2000, the ARSCL data set incorporated data from the
Beaufort Laser Ceilometer as one of its inputs.  Because of the BLC's
high spatial resolution, this data was often chosen by ARSCL as the
"CloudBaseBestEstimate" for boundary layer clouds. It was subsequently
determined that the BLC cloud base was biased, with the BLC reporting
cloud base heights that are 122 meters too high.

The bias error will be corrected when the entire ARSCL data set is
reprocessed as part of release_4.  (The release version number is included
the the netCDF global comments).   This reprocessing will also include a
small correction the the MMCR near-field reflectivities.  This correction
is less than 1 dB except for hydrometers within 200 meters of the surface.

Thanks to Roger Marchand for helping bracket this problem.

SGP/MMCR/C1 - Power supply failure
DataStreams:sgparsclbnd1clothC1.c1
Description:
A power supply failed in the MMCR's receiver.  During the period of this DQR, the radar 
would appear to work but the calibration is probably incoorect during good portions of this 
time.  The power supply was replaced and normal operation resumed at 2115 on 02/11/2005.

DQR category: 4 (Red, Incorrect).

The new phase shifter had the delay lines reversed, which resulted in the beams going in 
the wrong directions.  The speeds are correct and the directions are 180 deg off.

SGP/RWP/C1 - Reprocessed and Corrected: Instrument in non-standard mode for IOP
DataStreams:sgp915rwpwindconC1.a1
Description:
DATA REPROCESSED and CORRECTED: 

In the moment datastreams (precipmom and wind mom) from the 915 RWP, the snr variable, is 
not set to missing value when the SNR is invalid but the other moments have valid values. 
At these points the SNR has a value of 32767. The ingest was updated and the data were 
reprocessed to fix the issue.

The data were Archived in July 2016. Please retrieve the reprocessed data for use in your 
analysis.

--- 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.

SGP/ARSCL/C1 - Ceilometer not used during processing
DataStreams:sgparsclbnd1clothC1.c1
Description:
The ceilometer was not used during processing due to a ceilometer data format change that 
ARSCL did not handle properly.  As a result, cloud boundaries in the lowest several 
kilometers may be less accurate than usual, as they are based solely on the micropulse lidar 
and millimeter cloud radar.

SGP Site Power Outage Due to Winter Storm
DataStreams:sgp915rwpwindconC1.a1
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.
