Description:
Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the February 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)       
----    -------  ------------   
02/05   WIST     RELH        - Cold-air drainage at this low-lying
                               site caused it to be spatially inconsis-
                               tent with neighboring stations; ignore
                               the flags.

02/08   CHEY     TAIR        - Station poked above the cold inversion
                               layer; disregard the flags.

02/13   CHEY     RELH, TAIR  - Station poked above the cold inversion
                               layer; disregard the flags.

02/23   MEDI     TAIR        - Station poked above the cold inversion
                               layer; disregard the flags.

02/25   BUFF     TAIR        - Station poked above the cold inversion
                               layer; disregard the flags.

02/28  CHEY,MEDI TAIR        - Stations poked above the cold inversion
