| Description: | Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the May 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)
---- ------- ------------
5/9 ERIC WSPD Localized thunderstorms produced
strong winds at ERIC; disregard
the flags
5/10 HOLL PRES Intense thunderstorm and meso-
high moved near the HOLL site;
disregard the flags
5/17 CHEY WSPD, WS2M Thunderstorm caused localized wind
gusts of 70 mph at this site; you can
ignore the flags
ERIC PRES | Strong thunderstorms and meso-highs
PUTN PRES |------- moved over these sites causing their
TIPT PRES | pressure observations to be spatially
off; disregard the flags
5/20 CAMA PRES Localized intense thunderstorm and
high wind gusts caused this site's
pressure observations to be spatially
inconsistent with neighbors; ignore
the flags
5/23 HASK WSPD Strong wind speeds to over 65 mph
associated with thunderstorms caused
this data to be flagged; disregard
the flags
5/26 TIPT WSPD Meso-low forming in advance of a
strong thunderstorm caused the strong
winds at TIPT; ignore the flags
