Can anybody come up with a chart showing CO2 atmospheric concentrations
as a function of altitude?

CO2 is 150% of the density of air so it should sink to the ground.

http://en.wikipedia.org/wiki/Carbon_dioxide
"At standard temperature and pressure, the density of carbon
dioxide is around 1.98 kg/m³, about 1.5 times that of air."

If you have a open top container of CO2 it will remain in the
container until it is poured out like you would pour water.

Paul,
There is essentially no difference in the concentration of CO2 with
altitude. The difference in density is overwhelmed by the convection
currents (thunderstorms and wind). Yes, a container of co2 will sit (for a
while) in a quiescent situation, but molecular diffusion will gradually
cause the gas to mix with the surrounding air.

Has anybody measured this? Are there any references ?
