RING PRES Continued to show spikes in pressure during the month,
notably on the 18th, 19th and 21st. The QA flags catch
these, but suggest the sensor may have been a bit
erratic. It is not unusable, though. |

One thing I noted was that MEDI TAIR on the 2nd had 53 suspect flags. These are probably false-alarms. MEDI and CHEY have some local effects which often preclude establishment of inversions, so they often get suspect flags on TAIR on calm, cool nights. We corrected the problem at half the sites with the like-instrument comparison routine (TAIR and 9-meter air temperature), but neither MEDI nor CHEY have TA9M installed. |

| Description: | Following is an assessment of the automated quality assurance runs for January and February 1996 from Mark Shafer: February was not terribly kind to the Mesonet. We had some problems with pressure readings in the early part of the month (1st - 5th). I think this was related to the early February ice storm which could have clogged pressure tubes. There were also numerous flags on TAIR during the month, especially at MEDI, CAMA, CHEY and COOK. I think these may have been attributable to the dry conditions last winter, with more variability in temperature from diurnal heating. I would disregard "suspect (1)" flags on TAIR during February. The same conditions were true for January. There were several instances of days with a number of PRES sensors being flagged, but I can't account for the cause of these at this time. I asked our QA manager to look into what might have been the culprit. The same pattern of TAIR appeared during January as well. |

Quality Assurance runs:
There are a few concerns for
this month's data (noted below).
PROBLEMS SITES:
---------------
BBOW PRES December 10-11 appeared erratic; self-corrected
BUTL RELH Numerous flags on the 2nd, flagged as bad on December 13;
repaired December 16.
CLAY LEAF A large number of failures during the 2nd - 11th; noted
as bad on April 22, 1996; repaired April 23.
COOK RELH Numerous failures on the 20th - 21st, perhaps due to low
battery voltage. Recovered.
NEWK SRAD Readings dropped below -1 at night from the 6th -13th,
and appeared low during the day. Flags ceased on the
13th. No trouble-ticket was noted, but a technician may
have replaced the instrument on a routine visit. |

| 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. |

| Description: | Below is a review by Mark Shafer of the automated quality assurance
for the October 1995 Oklahoma Mesonet data:
PROBLEM SITES:
--------------
ALTU LEAF A number of failures from the 20th - 29th. There was no
trouble-ticket, and it seems to have corrected itself
(or been fixed in-field by a technician).
CLAY LEAF Definitely bad the entire month. Numerous failures, but
not discovered until April 22.
GOOD LEAF Numerous failures from October 5 - November 1. No trouble
ticket issued, but looks good after November 1.
BYAR TB05 Suspect and Warning flags from the 1st through 12th. No
record of a trouble-ticket, but I suspect a bias was noted
and the sensor replaced on the 12th.
SULP TB10 Appears biased from the 2nd through 12th. It was eventually
flagged in our badparm record on March 22. Again, it might
have been corrected, but then went bad again later.
Also, the usual problems of inversions persisted, notably at MEDI, CHEY,
and COOK (TAIR and RELH received a number of suspect flags). KING TAIR
and TA9M were also flagged bad (10 readings) on the 24th ... I think this
was caused by a strong and very shallow inversion (> 10 deg C between
the 1.5 and 9 m sensors). It is the only case I have seen yet where
the like-instrument provided a false alert. |

| Description: | Below is an overview by Mark Shafer of the automated qa of the September
1995 Oklahoma Mesonet Data:
We didn't do very well with the leaf wetness sensors.
As I recall, this is a time when we were behind on production (we make
them ourselves), so we could not replace them very quickly. In any
event, it was a busy month for QA...
PROBLEM SITES:
--------------
KETC TB05 1-7 and 27th - suspect and failure flags. It looks like
it drifted. It was repaired on August 8, 1995, but it
appears that the sensor which was installed had some
problems of it's own.
KING TS30 1-7 and 20th - supect and failure flags. It was set to
warning (2) in the badparm file on 10/02/95. Probably
should be careful even with unflagged obs for this month.
KING TS10 13-16th - high scores on the spatial checks; trouble-ticket
issued on 09/16.
HOLL TS30 20-25th - suspect and warning flags, became failures.
Apparent sensor drift toward failure. No flag in the
badparm table, but likely repaired quickly (25th).
BYAR TB05 26-30th - similar problem, probable sensor drift. No
flag in badparm table.
ALTU LEAF 8-9th - several failures. Not bad, but problems re-occured
in October.
BESS LEAF 10-30th - sporadic failures, no flag in badparm.
CLAY LEAF 9-28th - sporadic failures, flagged failure in badparm on
04/22/96.
FTCB LEAF 18-23rd - sporadic failures, no flag in badparm.
GOOD LEAF 11-19th, 29th - sporadic failures, continued until November
1st. No flag in badparm.
IDAB LEAF 23-24th - sporadic failures, no flag in badparm. |

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.

It was a pretty messy month. Four of the
problem sites listed below are from high battery voltages. The concern
is that high voltage may affect the performance of some of the sensors.
I didn't see anything (except perhaps HOLL) which would indicate secondary
effects, but it is nevertheless a concern.
PROBLEM SITES:
--------------
BIXB BATV 6th - 21st, reported high voltages.
BURN BATV 1st - 4th, reported high voltages.
CHER BATV 6th - 26th, reported high voltages.
COOK SRAD 17th - 21st, low readings indicated by spatial test;
no flag in badparm (may have been caused by bird droppings,
cleaned up by a technician on the 21st).
HOLL BATV 1st - 21st, reported high voltages.
HOLL PRES 4th, suspect and warning flag may have been related to
battery problem.
HOLL SRAD 10th, seven suspect flags perhaps related to battery
problem.
KETC TB05 8th - 29th, began failing spatial and range checks;
flagged 3 in badparm on 07/01.
MADI TS05 1st - 4th, warning and failure flags; flagged 2 in
badparm on the 4th.
RING PRES pressure spikes on the 9th, 26th, 28th and 29th.
SALL SRAD 6th - 31st, readings dropped below -1 at night repeatedly.

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.

On the 7th and 8th there
were several pressure sensors (CAMA, CHAN, MAYR, MINC, SHAW, and
STIL) which had suspect and warning flags. The problems were noted
only during those two days for those sites, so I suspect there was
some sort of weather-related phenomenon which caused the problems.
I recall some discussion a couple of years ago about water getting
sucked up into the pressure tube and causing some blockage. I have
a feeling the further back we go, the more of these problems we
will see. I guess that's the nature of the learning curve when you
establish a network

--------------
CALV TS05 entire month, range failures. It was flagged as 3 in

FAIR TB10 23rd - 31st; failing spatial check. Badparm flag of 2
issued on 04/02; instrument apparently replaced on 05/09.
MEDI PRES 17th - 21st; every observations for those days flagged
either warning or failure. No badparm flag but problems
ceased on the 21st.
RING PRES 22nd - 29th; every observations for those days flagged
either warning or failure. Flag set to 3 in badparm on

| Subject: | Overview of Automated QA - January 1995 |
| DataStreams: | sgp05okmX1.a1, sgp15okmX1.a1 |
| Description: | Below is an overview by Mark Shafer of the automated quality
assurance results for the January 1995 Oklahoma Mesonet data.
Along with the usual concerns (inversions,
battery voltages, and leaf wetness sensors), there were a few more
pressure observations which looked bad over a couple of days but then
cleared up. I think these are attributable to water or ice in the
pressure tube. The sensors were: (MAYR - 4th, 7th; TAHL 4th-5th; and
ARNE - 7th).
There were also some inversions which caused flags on TAIR and RELH, which
I believe were inappropriate. The worst cases were: CHEY (2nd, 8th, 11th),
BUTL (11th), CHER (11th, 12th), MEDI (11th, 19th, 20th) and MINC (11th).
There may have been an icing event on the 20th - 24th. Wind speed standard
deviations were very low at VINI and PRYO on the 20th, HOBA, MANG, NINN,
and SEIL on the 23rd, and CHIC on the 24th. If WSSD was low for a site,
it is probably best to be cautious with any wind observations from the
site for the day.
PROBLEM SITES:
--------------
BBOW PRES 2nd - 6th; High spatial scores (ASI's) and suspect flags.
Flagged 1 in badparm on the 10th, flag cleared on 03/09.
This may be similar to the pressure problems noted above,
but it's characteristics were more of a general drift
rather than the spikes we see from clogged ports.
BBOW TS10 16th - 19th, started failing spatial and range tests.
Problem ceased after the 19th, but a flag was placed
on the site on 05/17 (flag 1) and upgraded to 2 on
06/08. The sensor was apparently replaced on 06/13.
This may have been an early indication of a problem
which persisted into June.
CALV TS05 11th - 31st; Began failing range test on the 11th, and
continued failing until flagged 3 in badparm on 05/17;
replaced or repaired on 06/28. I suspect a critter may
have chewed through the wire.
GOOD PRES entire month; 288 warning flags daily - probably indicates
the sensor got 'stuck' at some reading. It was flagged
as 2 in badparm on the 27th, upgraded to 3 on 02/16 and
repaired 02/23.
KING RELH 26th; not a bad problem, but noticed a flag of 1 in badparm
later on on 04/03 - 04/06. It's probably ok to use these
readings with the qa flags, but it could be an early
indication of a problem.
MADI TB10 29th - 30th; high spatial scores. Flagged 2 in badparm
on 02/16, remained flagged until 07/28.
MEDI RELH 26th - 27th; numerous failures of range test; flagged 3 in
badparm on 03/13, problem corrected on 03/14.
BATV sporadic problems at BURB (1st), NORM (24th) and BURN (27th).
LEAF Persistent problems: BOWL (2nd), FTCB (1st), GRAN (1st),
PAUL (1st) and TIPT (1st).
Sporadic problems: LAHO (3rd), MARE (9th). |
