Review of automated quality assurance for June 1996

Overview of automated quality assurance runs for June 1996 by Mark Shafer:
PROBLEM SITES:
--------------
BUTL SRAD       Readings dropped below -1 at night (edge of instrument
                error).  No trouble-ticket was issued, but I believe it
                was later investigated.  Errors appear minimal and
                should not affect daytime readings significantly.

ACME PRES       From 3rd-6th received several warning and suspect flags.
                No record of trouble-ticket, but problems stopped after
                the 6th.

REDR TB10       Numerous flags from the 16th-21st.  Monthly visual
                inspection indicated a large warm bias, and some readings
                were more than 30 deg F different than TS10.

NORM TS05       4 deg C warm bias during month, ongoing through July.

* any of these sites should be OK to use with the information contained
  in the corresponding QA files.  I'm just trying to give a "heads up"
  for sites which seemed to have persistent problems in case some
  particular readings slipped past QA thresholds.

Users of these data should review the automatically generated 
quality assurance files.
