SGP/OKM - Overview of Automated QA - March 1999
DataStreams:sgp05okmX1.00, sgp15okmX1.00, sgp15okmX1.a1, sgp05okmX1.a1
Description:
Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the March 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)       
----    -------  ------------   
03/01    MEDI     TAIR        - Station poked above the cold inversion
                                layer; disregard the flags.

03/15-16 MEDF     TAIR        - Isolated deep snow cover caused this
                                station's temperatures to be much
                                colder than neighbors; ignore flags
