Description: | Below is an overview from Mark Shafer of the automated quality
assurance results for the October 1997 Oklahoma Mesonet data.
1. CLAY RELH may have been slightly high all month. It failed the
range test on several occasions, but only for a few observations per
day. The QA manager did not think it was bad enough to warrant a
trouble-ticket.
2. EUFA RELH had a number of failures on the 16th-17th (correctly
flagged). A trouble ticket was issued on the 20th. I would advise
caution from the 16th onward.
3. MEDI TAIR had 13 suspect flags on the 15th - these can be ignored.
They resulted from nearby stations getting nocturnal inversions while
MEDI stayed mixed.
OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
for the month of October, 1997
Based upon observations taken at 1800 UTC each day
Prepared by Jerry Brotzge (jbrotzge@ou.edu)
================================================================================
Notes: Greetings all...
October heralded the return of much cooler temps to the state with
rapidly changing weather conditions. Fortunately, the Mesonet instruments
handled the colder temps and occasional precip quite well. Relatively few
new problems were reported.
This month's wildlife includes: gophers at WOOD and ARS, worms in
the pres tube at HUGO, and spiders at ARS. The highlight of the month:
an armadillo at REDR playing with our soil probes.
