Re: Altitude vs. Barometric pressure (OR...)
OR... you can buy a Horus/Kestrel 4500 with the newer Applied Ballistics program and let it figure all this out for you, including such other niceities as coriolis effect, wind drift, etc. That device plus an accurate laser rangefinder will give you a very accurate firing solution.
"Altitude density" is the actual term for this barometric pressure conundrum. And that, of course is affected greatly by temperature and humidity.
