| Description: | Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the August 1998
Oklahoma Mesonet data.
here are a few special events that were flagged by the automatic qa that
you may want to be aware of. These include:
* BRIS TS05 - (August 1 - August 31) The automatic QA created 15-20
suspect
flags and a few warning flags each day for this site. We believe the
sensor to be ok; however, the sod plot overlying the sensor was likely
dead due to the drought this summer. The data should be used with
caution.
* The following list includes stations which experienced significant
thunderstorm outflow. These events were usually isolated in nature, and
therefore the data (typically TAIR) appeared to be spatially "off". We
have
investigated these events, and deem the data to be good. You can ignore
the flags:
OILT TAIR (August 2)
TALI TAIR (August 3)
ARDM and MTHE TAIR (August 7)
BOWL TAIR (August 8)
BREC TAIR and HOBA TA9M/TB05 (August 10)
MTHE TAIR (August 12)
PAWN TAIR (August 13)
COPA TAIR (August 26)

OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT
for the month of August, 1998
Based upon observations taken at 1800 UTC each day
Prepared by Chris Fiebrich (qamgr@redrock.ocs.ou.edu)
===========================================================================
=====
Notes:
The NINN site was moved approximately 7 feet from its original location
on August 18 due to a water main break underneath the site.
It really WAS that dry... The technicians checked a number of rain gauges
during the month that were suspected of under-reporting. HOLL was high on
the list, since the site had observed only .03 inches of rainfall over the
past 90 days. The gauge checked out fine, and Bill Wyatt reported that
"the general appearance of the area indicated that children as old as 4
or 5 may not have seen rain in their lifetime."
We also had a handful of soil temperatures flagged as 'suspect' because
they have been repeatedly failing the spatial test during the hot after-
noons. The recent rainfall across the state will hopefully help us better
evaluate which sensor are biased, and which sensors are simply reporting
the conditions of the dry cracked ground.
And now, on to the report...
