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;

         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

                                   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

6/25     HOLL       WSPD           Wind gusts to 63 mph caused this site
                                   to be spatially inconsistent with 
neigh-
                                   bors; you can disregard 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.
