There is a general assumption is that CO2 is well mixed in the
atmosphere. I'm trying to find any documented measurements of the CO2
vertical profile that would confirm this. I found this
http://cdiac.ornl.gov/ndps/ndp007.html which covers a small range of
altitudes. Other than that what I've seen so far are mostly either surface
measurements or column averaged values.

carbon dioxide boundary layer measurement
carbon dioxide vertical profile

Biologists have been making such measurements for many decades.
The carbon cycle is biological, every ecosystem has people who do this,
marine, tropical forests, farm/grasslands, boreal forests, etc.
