KEY:
     IN "R.CODE" COLUMN:
                                           B - OCCURS ONLY IN THE GFS/GDAS AND CDAS VERSIONS OF OIQC (THE OIQC STEP DOES NOT RUN IN ANY OTHER NETWORKS).   As of 02/24/2009 1200 UTC, the GFS and GDAS GSI analyses no longer honor the decisions made in this step.  Instead, the GFS/GDAS GSI now runs its own internal variational quality control on the observations.
     IN “MNEMONIC” COLUMN:
                                           #  - NEW VALUE CALCULATED.
 
 

R.CODE	MEANING	MNEMONICS AFFECTED AND NEW VALUE FOR OBS, Q.M.
02 B	SSM/I OCEANIC WIND SPEED REPORT.  PERFORMS A MULTIVARIATE SURFACE WIND ANALYSIS AND ASSIGNS THE ANALYZED DIRECTION TO THE WIND SPEED OBSERVATION.  THEN GENERATES NEW U- AND V-COMPONENTS FOR THE WIND VECTOR.	WRC-> UOB,VOB= #, WQM= 2
04 B	OBSERVATION ORIGINALLY WITH A KEEP FLAG (=0)IS REJECTED BECAUSE IT IS MORE THAN 20 TIMES THE EXPECTED DIFFERENCE FROM THE INTERPOLATED NEARBY INDEPENDENT INFORMATION.	PRC-> PQM=4 TRC-> TQM=4 WRC-> WQM=4
05 B	OBSERVATION ORIGINALLY WITH A GOOD QUALITY MARK (=1) IS REJECTED BY THE OIQC CHECKING ALGORITHM.	PRC-> PQM=5 TRC-> TQM=5 WRC-> WQM=5
06 B	OBSERVATION ORIGINALLY WITH A NEUTRAL QUALITY MARK (=2) IS REJECTED BY THE OIQC CHECKING ALGORITHM.	PRC-> PQM=6 TRC-> TQM=6 WRC-> WQM=6
07 B	OBSERVATION ORIGINALLY WITH A SUSPECT QUALITY MARK (=3) IS REJECTED BY THE OIQC CHECKING ALGORITHM.	PRC-> PQM=7 TRC-> TQM=7 WRC-> WQM=7
