Yes, the __amibent levels__ will lower as you go up in altitude. Doesn't imply the actual levels with respect to dosing CO2 and the plant's O2 production will be less/more.
The ratio of C13, C12 and C14 should stay the same even if the amount of gas is less.
There may be some conversion for high altitude Carbon dating, but I think under 2000-3000 meters, it would fairly consistent.
my question is how CO2/O2 change with altitude? increase? decrease? or keep constant?
and another question is if the carbon isotope compostion of CO2 change with altitude?
