[wxqc] Barometer Errors

[George Prevelige]

I try not to take it personally when I receive a whole page of errors in my
daily Weather Quality Report. But this barometer issue is starting to bother
me.

90% of the time, my report is error free. But, periodically, normally before
a front comes through, my barometer readings deviate above the margin of
error. I understand that a front can cause local anomalies, but what about
the times between fronts when I get these errors (like today - I had 51/96
barometer errors, 0/96 for all other readings)? 

Before I start tweaking my barometer, are there any other explanations for
my readings to be 2 to 3 MB (usually lower than sample) off the reference
data, only to be back in sync a day or two later?

Others have voiced concern about incorrect or absent comparison data near
their site. There are no sites within 10 miles of my station that have
consistent or even useable data.
