SGP/OKM - Overview of Automated Data Quality - February 2001

Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the February 2001
Oklahoma Mesonet data.



3 more ice storms hit the state during February.  The first
storm lasted from the 8th through the 11th and affected much 
of northwest Oklahoma.  The second event lasted from the 15th 
through the 18th and affected 27 stations in south-central 
and east-central Oklahoma.  The third event affected over 40 
stations in central and northeastern Oklahoma on the 28th 
of the month.  Wind data from these events was flagged
appropriately in the QA database.

HUGO became the first site to get struck by lightning during
2001.  On the 24th, the site suffered major damage to the 
logger, battery, rain gauge, temperature and RH, and
soil temperatures sensors.
