SGP/OKM Overview of Automated QA - June 2000

Below is an overview from Chris Fiebrich, the Mesonet QA manager
of the automated quality assurance results for the June 2000
Oklahoma Mesonet data.

===============================================================
Notes:
The Mesonet Technicians completed Spring Pass 2000 on June 30.
The point comparisons they performed on the TAIR, RELH, PRES,
SRAD, and RAIN parameters were very useful for QA of Mesonet
data.  A number of sensors reporting slightly outside of the
Mesonet's acceptable error ranges were identified.

Many site photos were taken during Spring Pass 2000 to document
vegetation cover around the bare and sod soil temperature plots,
the soil heat flux sensors, and the soil moisture plots at each
station.  Look for those pictures along with the site visitation
forms indicating the technician's notes to be available on the 
web next month.

One more note... The monthly analysis for June identified the
very heavy rains that fell over east Oklahoma during mid to late
June.  Westville took top honors with a June total of 
17.04 inches!
