| Description: | Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the June 1999
Oklahoma Mesonet data.
There are a few special events that were flagged by the automatic
qa that you may want to be aware of:
Date Station Parameter(s)
---- ------- ------------
6/1 FTCB,HOBA PRES Intense thunderstorm and meso-high
moved near the FTCB and HOBA sites;
disregard the flags
HOLL PRES Intense meso-low moved near the
HOLL site; disregard the flags
MAYR WSPD Thunderstorm winds to 85 mph
at MAYR caused it to spatially in-
consistent with neighboring sites;
you can ignore the flags
MAYR PRES Meso-low; disregard the flags
RETR PRES Meso-high; disregard the flags
6/2 SALL PRES Meso-high; disregard the flags
6/3-6/30 MAYR SRAD Faulty relative humidity sensor
caused the solar radiation readings
to dip slightly below zero over night
(ie, to -1 or -2 Watts/m^2). The
data is fine, however, and you can
ignore the flags
6/24 SULP PRES Intense meso-high; disregard the
flags
6/25 HOLL WSPD Wind gusts to 63 mph caused this site
to be spatially inconsistent with
neigh-
bors; you can disregard the flags
6/29 MTHE PRES Meso-high; disregard the flags
SALL WSPD Wind gusts to 77 mph; disregard the
QA flags
6/30 MINC,WASH PRES Meso-low; ignore the flags

OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT
for the month of June, 1999
Based upon observations taken at 1800 UTC each day
Prepared by Chris Fiebrich (qamgr@redrock.ocs.ou.edu)
=======================================================================
Notes:
Lightning struck at WALT, OKEM, and A182 during June. All 3 sites suf-
fered damage to their dataloggers, radios, and wiring panels. In
addition, the pyranometer and RH sensor at OKEM were damaged, while the
soil moisture sensors, rain gauge, and numerous soil temperature
sensors were damaged at WALT. A182 also required a new pyranometer
due to its strike.
After thorough Mesocomp performed by Ken Meyers in the ARS network,
numerous T/RH sensors were replaced in late June and early July
in anticipation of SGP99.
