Description: | Mark Shafer has provided the following overview of the results of
the automated quality assurance for the June 1995 Oklahoma Mesonet data:
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.
LEAF Persistent problems at: KETC (1st), MARE (1st), BOWL (3rd),
LAHO (12th) and CLAY (13th).

Description: | low is an overview by Mark Shafer of the automated quality
assurance results for the March 1995 Oklahoma Mesonet data.
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
PROBLEM SITES:
--------------
CALV TS05 entire month, range failures. It was flagged as 3 in
badparm on 05/17; apparently repaired on 06/28.
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
the 27th; instrument apparently relaced on the 29th.
BATV BURB (3rd), BURN (1th), CHER (24th) and COOK (25th).
All problems appeared sporadic. COOK TS10 and TB10
also had 7-8 failures on the 25th, perhaps attributed
to battery voltage problems.
LEAF Persistent problems: FTCB (1st), GRAN (1st), IDAB (4th),
MARE (2nd) and PAUL (1st).
Sporadic problems: ALTU (8th), BOWL (8th), CLAY (16th),

|
Description: | 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).

|
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).

Description: | OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
for the month of March, 1997
Based upon observations taken at 1800 UTC each day
Prepared by Jeff Basara (jbasara@ou.edu)
================================================================================
Notes:
It was kind of a miserable month for parts of the Mesonet. In eastern
Oklahoma, both SALL and PRES were vandalized with SALL receiving extensive
damage, and PRES sustaining some moderate damage. What kind of idiots would
be so stupid as to rip off or destroy a bunch of "weather instruments"? I
would bet that they don't realize that there is not a tremendous black market
for these types of things.
Then there are the usual Mesonet occurences. Gophers continue to play havoc
with anything buried in the ground. Plus, parts of western Oklahoma received
either little or no precipitation for the entire month of March. At some
sites this may be suspect since there may be clogged gauges.
Once again we enter the time of year where convective storms produce lightning.
Although there has not been apreciable damage due to lightning thus far, it
wll only be a matter of time before the first site takes a major jolt.
And now, the information you've all been waiting for ...

Mark Shafer adds:
... there are occasionaly some
TAIR and/or RELH readings flagged as suspect due to inversions. The
most frequently affected sites are BUFF, CAMA, CHEY and MEDI, although
others occassionaly show up. These false alarms are a recognized
limitation of the automated qa programs. We corrected the problem,
where possible, through comparisions with 9-meter air temperature, but
because those sensors are only at half the sites, that leaves half the
network susceptible to inversions problems. Otherwise, the data flags
appear to match the QA manager's report. |

Description: | Following is an overview of the April 1997 Oklahoma Mesonet Automated
Quality Assurance Data Files
From Mark Shafer, Oklahoma Mesonet
The April report from the QA manager is
attached here. The only thing I would add is that WEBB RELH and
SALL TAIR and RELH appeared to have some problems not documented.
The indiviudal data have flags which reflect problems, but I would
be cautious with RELH data for these two sites.

OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
for the month of April, 1997
Based upon observations taken at 1800 UTC each day
Prepared by Jeff Basara (jbasara@ou.edu)
================================================================================
Notes:
As the weather warms up, it seems the Mesonet has also. The technicians have
had plenty of things to keep them busy, and many trouble tickets were issued
and resolved in April. With the onset of the spring rains, more rain guages
have shown up plugged or stopped. This has proven to be the most problematic
instrument during the month of April, but even so, the guages have been working
rather well so far.
There was only one incident of vandalism this month, and it was at WEBB again.
Someone decided they needed a 10m wind monitor to add to their collection, so
they came back and grabbed one.
One note of weather related interest involves the monthly summary of wind
vectors. With a number of surface low pressure systems slowly marching through
Texas in April, the 1800 UTC wind vectors were almost due easterly is southern
Oklahoma for the month. Rather interesting!
Well, here is the rap sheet...
