Description:
OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
       for the month of March, 1997

       Based upon observations taken at 1800 UTC each day

       Prepared by Jeff Basara  (jbasara@ou.edu)

================================================================================

Notes:

It was kind of a miserable month for parts of the Mesonet.  In eastern 
Oklahoma, both SALL and PRES were vandalized with SALL receiving extensive
damage, and PRES sustaining some moderate damage.  What kind of idiots would 
be so stupid as to rip off or destroy a bunch of "weather instruments"?  I
would bet that they don't realize that there is not a tremendous black market
for these types of things.

Then there are the usual Mesonet occurences.  Gophers continue to play havoc
with anything buried in the ground.  Plus, parts of western Oklahoma received
either little or no precipitation for the entire month of March.  At some 
sites this may be suspect since there may be clogged gauges.

Once again we enter the time of year where convective storms produce lightning.
Although there has not been apreciable damage due to lightning thus far, it
wll only be a matter of time before the first site takes a major jolt.

And now, the information you've all been waiting for ...

Mark Shafer adds:

... there are occasionaly some
TAIR and/or RELH readings flagged as suspect due to inversions.  The
most frequently affected sites are BUFF, CAMA, CHEY and MEDI, although
others occassionaly show up.  These false alarms are a recognized 
limitation of the automated qa programs.  We corrected the problem,
where possible, through comparisions with 9-meter air temperature, but
because those sensors are only at half the sites, that leaves half the
network susceptible to inversions problems.  Otherwise, the data flags
appear to match the QA manager's report.
