Description:
Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the April 1999
Oklahoma Mesonet data.

There is one special event that was flagged by the automatic 
qa that you may want to be aware of:

Date    Station  Parameter(s)

       OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT
       for the month of April, 1999

       Based upon observations taken at 1800 UTC each day

       Prepared by Chris Fiebrich (qamgr@redrock.ocs.ou.edu)

========================================================================
Forces of Nature:
SHAW, SALL and CLAY were each struck by lightning during the month
of April, causing varying degrees of damage to the instrumentation
at those sites.  CLAY is no stranger to lightning strikes.  This was
its third strike since its birth in March of 1994.  As a preview to 
next month's QA report, I'd like to note that CLAY saw its FOURTH
strike just last week!

Bulls were reported to have attacked BRIS during April, knocking down
a pyranometer stand, destroying the temperature and RH sensor, and 
causing damage to the rain gauge there.

Mischievous cows also knocked down the pyranometer stand at WASH.

On to the report...
