Remember, it's the barometer AT SEA LEVEL. So in Denver, the barometer AT SEA LEVEL would be a NEGATIVE 5280.
So what you're saying is that my z-axis is upside down?

I confirmed all of the OP's weather station results do seem to match when I run them through the weather correction calculator. I still thought the weather stations all used "station pressure" because they had no way to know the value of sea-level perssure. I know I read that a while ago...but I'll definitely keep digging into it.

Thanks again for the info.
