SGP/OKM Overview of Automated QA - October 1999
DataStreams:sgp05okmX1.00, sgp05okmX1.b1, sgp15okmX1.b1, sgp15okmX1.a1, sgp05okmX1.a1, sgp15okmX1.00
Description:
Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the October 1999
Oklahoma Mesonet data.


There are a few special events in the October data 

Date    Station  Parameter(s)       
----    -------  ------------   
10/02   TALI     TAIR         -| Strong low-level inversion caused many 
10/13   CHEY     TAIR          | sites which "poked" into the warmer air
10/20   CHEY     TAIR          | to be spatially inconsistent with neigh-
10/20   MINC     TAIR          | boring stations.  You can disregard the 
10/26   CHEY     TAIR         -| flags for these stations.

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

       Based upon observations taken at 1800 UTC each day

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

=======================================================================
Notes:

Over 375 trouble tickets were issued and reconciled during October-- 
mainly due to OASIS upgrades.  Here's a summary of the tickets that
directly affected our data quality.
