[wxqc] bar errors

[Al Huggard]

Phillip, don't understand.  My bar reported on findu page is exactly as it 
is on my VWS display.  I understand this is raw data.  When, however, I look 
at the graphs for my station they show a 6 to 10 millibar positive error. 
My bar is very close to the weather underground stations in the area and 
when converted from millibar to inches of mercury the VWS bar reading is are 
very very close to my old analog barometer that hags on the wall.  As I 
said, I don't understand.  seems it should be all the same.  I do note to 
the VWS reports very little difference between raw and sea level bar 
readings but I  chalk that up to my less then 1000 ft elevation.  Can you 
shed any light on this anomaly?
