Overview of Automated QA - August 1995
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Below is an overview by Mark Shafer of the August 1995 Oklahoma Mesonet 
automated quality assurance runs.

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

KETC  TS05      Suspect flags from the 1st - 11th; no flag in badparm.

KETC  TB05      Failed range check often from the 8th - 31st.  A trouble-
                ticket had been issued on July 1, 1995 and was resolved
                on August 6.  However, the problem apparently persisted.
                I am not sure of the cause.

KING  TS30      Suspect and failure flags the entire month.  Flagged as
                warning on October 2.

KING  TS10      Large spatial scores from the 5th - 7th.  Flagged as 
                warning on September 16.

SALL  SRAD      Dropped below -1 at night from the 1st - 25th.  Apparently
                replaced on August 25.

HOLL  TS30      Failures in range test from the 3rd - 5th.  No flag in
                badparm.

RING  PRES      Several pressure spikes during the month (5th, 12th, 17th,
                20th).  This is confusing because it is the only Mesonet
                site which has repeatedly shown these patterns.  It could
                be an interesting study :-)  The typical pattern of a
                pressure spike will show up in the .qbd file as:
                RING PRES     1     0     1     0
                The 1 failure is from failing both the step and spatial
                tests.  On the way back down, it fails the step, but
                passes the spatial which leaves a suspect flag (instead
                of a warning). 

LEAF            Rather than listing them separately, it appears that
                a number of sites had persistent problems.  The
                date first noticed is indicated in parentheses.
                BESS (1st), BOWL (1st), KETC (1st), ALTU (4th),
                LAHO (7th), GOOD (15th), CLAY (24th), IDAB (24th)
