Subject:
Overview of Automated Quality Assurance for August 1996
DataStreams:sgp15okmX1.a1, sgp05okmX1.a1
Description:
Review of automated quality assurance runs for August 1996 by Mark Shafer:
There were a few stations / parameters of which to be 
suspicious.  MARS TS10 showed an 8-9 degree warm bias,
but a trouble ticket was not issued until Sep. 24.  It
apparently wasn't enough to consistently trigger any
flags.  COPA TS10 also appeared suspect from August 1-10.
ALTU BATV appeared low during the 16-20th, and a trouble-
ticket was issued on that Sep 29.  The voltage was
actually reading too high, so I doubt there was any
effect on the instruments.

Otherwise, the QA seemed to match reality, more or less
(given the usual problems of local effects, inversions,
dryline passages, etc.).
Suggestions: 
Users of these data should review the automatically generated
quality assurance files.
