In this work, the determined refractive indices of Carbon Dioxide gas in terms of both CO2- temperature and CO2-pressure were used to determine the transport phenomena of this gas with the atmosphere. The transport phenomena was indicated with the transport coefficient which means the viscosity coefficient η, the diffusion Coefficient D, and thermal conductivity χ of CO2. The values of these coefficients were determined and its behavior depending on both pressure and temperature of the investigated gas, CO2. The rate of change of these coefficients with respect to CO2-pressure at constant temperature of CO2, (dD/dp)T,λ, (dη/dp)T,λ, and (dχ/dp)T,λ were determined. In addition, the rate of change of the same coefficients with respect to CO2- temperature at constant CO2-pressure (dD/dT)p,λ, (dη/dT)p,λ, and (dχ/dT)p,λ were also determined. All of these parameters were investigated at selected laser wavelengths, 476, 488, 502, and 514.5 nm. The graphs shown were at λ=488 nm as an example.
