Perfect for residential, commercial, industrial HVAC or IAQ applications 2011-08-18 · So over a very long length, 390 ppm is a LOT of CO2. The atmospheric pressure drops as elevation increases. For the total atmosphere (40 kilometers for calculation purposes), at 100 ppm CO2 throughout, the path length will be somewhere around 67 bar cm (using the ‘standard atmosphere’ equation for change in pressure with elevation). So 950 micro atm (950E-6 atm) CO2 in 1 atm air will be equivalent to 950 ppm of CO2. Cite. 7 Recommendations.
