Overview of Automated QA - February 1995

Below is an overview by Mark Shafer of the automated quality
assurance results for the February 1995 Oklahoma Mesonet data.

There were apparently some
inversions which caused flags in TAIR and RELH at several stations:
CHEY (1st, 17th), COOK (1st, 20th and 22nd), MEDI (1st, 2nd and 20th),
FAIR (20th) and MINC (20th).  There were also a number of leaf wetness
sensors flagged by the persistence program on the 13th, aside from the
usual suspects listed below.  Otherwise, the flags appear accurate.

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

ALTU  SRAD      24th - 28th.  Failing spatial and range tests.  Flagged
                3 in badparm on 03/01, replaced on 04/19.

BBOW  TS10      17th; only showed up one day (from spatial test), but
                flagged 1 in badparm on 05/17, upgraded to 2 on 06/08,
                and replaced on 06/13.  It's probably OK to use with the
                flags, but be a bit extra cautious.

CALV  TS05      entire month.  Flagged 3 on 05/17; replaced on 06/28.

CHAN  TA9M      1st - 7th; flagged 3 in badparm on the 7th.  Replaced
                on 02/16.

BATV            sporadic problems at BURN (beginning the 2nd), BURB (5th),
                and NORM (8th - but became much more frequent later in
                the month).

LEAF            Persistent Problems: BOWL (1st), FTCB (1st), GRAN (1st),
                MARE (1st), PAUL (1st) and TIPT (2nd).
                Sporadic Problems: LAHO (5th), ALTU (8th).
