Subject:
Overview of Automated QA - November 1995
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Below is an overview by Mark Shafer of the results of the automated quality
 assurance procedure applied to the Oklahoma Mesonet data.
PROBLEMS SITES:
---------------

CLAY LEAF       failed numerous range tests throughout the entire month.
                Not issued a trouble-ticket until April 22, 1996.  Ongoing
                problem which began at least as early as September 1995.

MADI WSPD       sporadically reported values of -7999 from the 16th - 20th.
                The QA caught the bad obs, but the sensor seemed "jumpy"
                during this time so I would excercise a little extra
                caution if using this site from that time frame.  The
                readings also affected WVEC and WSSD.  WDIR looked ok,
                but meaningless without the vector magnitude (WVEC).

Otherwise it was just the normal inversions creating some erroneous
suspect flags on TAIR and RELH, especially for MEDI and CHEY.  The  
serious flags all looked fine.
Suggestions: 
Users of these data should obtain the automated quality assurance
files from ARM
