Description:
Overview of results of quality assurance automated tests for January 1997
by Mark Shafer:
The only major concerns I have from the January QA files is that there
were several episodes where Leaf Wetness sensors were flagged as suspect
by the persistence routine, perhaps erroneously.  We may have our threshold
on persistence for Leaf Wetness still a bit too high. 

Since the flags are only suspect it
should not really cause problems.  There were also a number of pressure
sensors flagged on January 17 (see 19970117.QBD).  I think these were
correctly flagged.  I am not certain, but it may have been related to
ice clogging the presssure port.  The stations which were flagged were
pretty much in a consistent geographical area.
Suggestions: 
Users of the data should review the January 1997 automatically
generated QA files.
