Overview of Automated QA - February 1997

Following is an overview by Mark Shafer of the results of the automated quality
assurance runs for the February 1997 Oklahoma mesonet data.

The February data looked pretty good.  There were quite a few suspect flags
on WSSD and TA9M from the 6th - 7th (from persistence).  I would discount
all these flags for those two days.  There were very few persistent 
problems (unlike what we are finding with the 1995 data!).
 

PROBLEM SITES:
--------------

LANE  TS05      Started failing spatial test on the 21st; flagged as 2
                in badparm on the 26th.

STUA  PRES      Appeared suspicious on the 21st - 22nd, then corrected
                itself.

WEBB  RELH      11th - 23rd; number of range-test failures.  Apparently
                replaced on the 23rd.
