Subject:
Overview of Automated QA - November 1997
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Below is an overview from Mark Shafer of the automated quality
assurance results for the November 1997 Oklahoma Mesonet data.
1.  CLAY RELH failed 1-2 observations almost daily.   No trouble-ticket,
but be cautious.

2.  STIL LEAF failed a number of obs on the 5th and 16th; a
trouble-ticket was issued on December 13.

3.  PUTN BATV  (battery voltage) was erratic from the 6th - 11th; a
trouble-ticket was issued on the 15th and cleared on the 24th.  There is
some possibility that low battery voltage may impair the performance of
some sensors and high battery voltage may over-excite some sensors.  I
suggest caution with ANY parameters from PUTN for the 6th - 24th.

4.  CHEY TAIR was flagged suspect on the 19th, 25th, and 26th; probably
the result of inversions at nearby sites.  CHEY is at a bit higher
elevation and gets fewer inversions, consequently staying warmer at
night which results in erroneous flags from the spatial QA.

5.  WSSD was "stuck" (persistance indicated virtually no change) for
FREE, ALVA, FAIR, LAHO and KING in NW OK and for NOWA, MIAM and VINI in
NE OK on the 13th, probably stuck from freezing rain.  Caution is
advised for any parameters from these sites because ice can encase the
radiation shield or plug a pressure port too.

       OKLAHOMA MESONETWORK QUALITY ASSURANCE REPORT
        for the month of November, 1997

        Based upon observations taken at 1800 UTC each day

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

 Notes: Greetings all...
         And the cow jumped over the ... Mesonet fence?  Not quite, but one did
 get into the EUFA site, disturbing most of our soil probes and breaking an RH
 probe (see Oct report).  EUFA should now be back to normal.  Fortunately, most
 other sites remained relatively quiet.
         November's weather marked a rather rude introduction to winter.  Average
 temperatures dropped about 10C statewide, with the average wind dir shifting
 from SE during Oct to NW during Nov.  Rainfall varied greatly across the state,
 too.  MTHE received 157mm while KENT received only 4mm.  And that 4mm was more
 than likely frozen.  Most of the state got about 30-40mm.

         So, overall an average month in the OK Mesonetwork.  Here are the
 specifics....
