Overview of quality assurance for May 1996
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Review of automated quality assurance runs for May 1996 by Mark Shafer:
May looked remarkably clean with
very few things not caught by QA.


PROBLEM SITES:
--------------

HINT SRAD       Readings went below -1 at night from May 1 (probably 
                beginning earlier) through May 20, generating numerous
                failure (3) flags.  It should not compromise the daytime
                readings.  Sensor was apparently replaced on May 20.

DURA PRES       Seemed to go a bit erratic on the 24th, but no other
                flags for the month.  Reason I would be concerned is
                that a trouble-ticket was eventually issued for it
                on June 8th.  It's probably ok to use with the QA
                flags applied, but may want to look closely even if
                flags are not indicated.
Suggestions: 
Users of these data should review the automatically generated
quality assurance files.
