Atmospheric pressure and density decrease with altitude exponentially!!!
Units: 1 bar=1000 mbar
1 Standard atmosphere: 1013 mbar
by the weight of the atmosphere above
the open air surface.
At higher altitudes, no need for altitude correction: what you measure is what you plot
Typical values for the atmospheric pressure at various altitudes
Sea-level: 1000 mb
3 km: 700 mb
5.6 km: 500 mbConstant height charts
