Overview of Automated QA - May 1995
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Following is an overview by Mark Shafer of the automated quality assurance applied
to the may 1995 Oklahoma Mesonet data.
There were some ongoing
problems with battery voltage at several sites and the usual
leaf wetness sensor problems.


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

CALV  TS05      1st - 17th; sensor definitely bad during this time.  Flagged
                bad (3) in badparm on the 17th; repaired 06/28.

KETC  TS05      11th - 16th, failing spatial test (suspect and warning
                flags, mostly).  Blagged 1 in badparm on the 16th; repaired
                06/05.

MADI  TS05      25th - 31st, failing spatial check.  Flagged 2 in badparm 
                on 06/04; repaired 07/28.

PAUL  TB10      6th - 16th, high ASI values (spatial scores).  Flagged 2 in
                badparm on the 16th; repaired 06/05.

RING  PRES      15th, another pressure spike.

SPEN  TAIR,RELH T&RH sensor taken out by a horse (used it as a scratching
                post) on the 1st; replaced on the 2nd.

STIL  TB05      2nd - 4th, suspect and failure flags from spatial and
                range test.  No flag in badparm but looked fine after 
                the 4th.

TIPT  WDIR      3rd - 16th, noted substantially off by both visual inspection
                and spatial scores.  Sensor replaced on the 16th.

WEST  PRES      21st-22nd, a number of warning flags.  No flag in badparm,
                and data looked fine after the 22nd.

BATV            High voltages at BURB (beginning 8th), BURN (1st),
                CHER (8th) and HOLL (1st).

LEAF            Persistent problems at: GRAN (2nd), IDAB (2nd),
                LAHO (13th), MARE (1st), and PAUL (2nd).
                Sporadic problems at: BOWL (14th) and CLAY (3rd).
