Description:
Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the October 1998
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)       
----    -------  ------------   
10/05   SHAW     WSPD,WVEC,PRES Tornado passed very close to station; we 
believe
                                wind and pressure observations to be 
accurate, despite
                                the flags.

       OKLAHOMA MESONETWORK/ARS QUALITY ASSURANCE REPORT
       for the month of October, 1998

       Based upon observations taken at 1800 UTC each day

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

===========================================================================


Notes:

It's been a busy month for the Mesonet technicians.  During October, 74
"fix tickets" were completed.  That includes replacements, repairs and 
rotations of sensors in the network.  

After the abuse the thirsty Oklahoma soil took over the summer, we were 
able
to replace 20 soil sensors in October.  Gophers were the culprit for
soil temperature problems at BRIS, SALL, and PERK, while erosion caused
biases in the data at IDAB and BOIS.  

Now that the Oklahoma skies have remembered how to rain again, we've been
able to pinpoint a number of rain gauge problems and get them repaired.  
The gauges at HOLL, PERK, TISH, ADAX, and COPA were repaired during
October.

And now, on to the report...
