| Description: | Below is an overview from Mark Shafer of the automated quality
assurance results for the January 1998 Oklahoma Mesonet data.
In summary, January 1998 had extensive cloud
cover and fog during the first half of the month. TAIR, RELH, WSPD,
WVEC, WSSD, and WS2M were frequently flagged at many sites around the
state. The fog and light winds were the cause. A lot of these flags
were from the persistence routine, as temperatures, winds, and humidity
varied little throughout the day. The fog took it's toll on our sites
by the 13th, as low battery voltages started showing up at BLAC, FREE
and HASK. This could affect other sensors from the 13th - 15th.
Once the sunshine returned on the 16th, things returned to normal.
There were a few inversions (CHEY 24, 27th; MEDI 24, 29th) which were
improperly flagged. MADI RELH occasionally was out-of-range (about one
observation per day) from the 5th onward. It was flagged suspect on the
25th, but it is a low priority and we have not yet had a technician
available to check it out. I do not think there is any overall concern
with this sensor, but it is worth looking at closely.
OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
for the month of January, 1998
Based upon observations taken at 1800 UTC each day
Prepared by Chris Fiebrich (chris@mesnet.mesonet.ou.edu)
================================================================================
Notes:
January turned out to be quite a mild month weatherwise.
Average 1800
UTC temperatures were a couple of degrees C warmer for January than they
were
for December. The lack of fronts and exciting weather was also evident
in
a much lighter average wind field across the state for January.
All the monthly averaged fields for January looked quite
smooth. No
new problems were found. Other than sensor rotations, the techs worked
to unclog 2 more rain gauges this month in which spiders had taken up
residence.
In addition, several sites had to have soil temperature repairs caused
by
gopher damage.
Thanks to Jerry, Tim, Sherman, Mark, and Derek for helping me
get
settled into my new position as QA Manager!
