| Description: | Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the January 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)
---- ------- ------------
01/06 CHEY TAIR - Station poked above the cold inversion
layer; disregard the flags.
01/12 SALL TAIR - Cold-air drainage at this low-lying
site caused it to be spatially inconsis-
tent with neighboring stations; ignore
the flags.
01/18 MEDI TAIR - Station poked above the cold inversion
layer; disregard the flags.
01/19 WIST RELH,TAIR - Cold-air drainage at this low-lying
site caused it to be spatially inconsis-
tent with neighboring stations; ignore
the flags.
01/24 CHEY TAIR - Station poked above the cold inversion
layer; disregard the flags.
01/28 BBOW WS2M - Completely calm conditions held the wind
speed at 2-m at 0.0 m/s all day long;
this caused our persistence program to
flag the data. Disregard the flags.
01/30 CHAN,MIAM PRES - Wind gusts to 45+ mph caused pressure
spikes; ignore the flags.

OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT
for the month of January, 1999
Based upon observations taken at 1800 UTC each day
Prepared by Chris Fiebrich (qamgr@redrock.ocs.ou.edu)
===========================================================================
Notes:
After a fairly long dry spell, the last weekend of January brought 1 to 2
inch rainfall totals to most sites in the Mesonet. This event brought
to our attention an under-reporting gauge at NOWA.
Along with the rainfall, the Panhandle stations got quite a bit of
freezing rain and snow. The 10-m wind sensors were most affected
this time around. GOOD, BEAV, HOOK, and SLAP all had their
anemometers
freeze solid as the ice accumulated.
And now, on to the report...
