IUPAC definition : The spreading or scattering of a gaseous or liquid material. eddy diffusion in the
atmosphere is the process of transport of gases due to turbulent mixing in the presence
of a composition gradient. Molecular diffusion is the net transport of molecules which
results from their molecular motions alone in the absence of turbulent mixing; it
occurs when the concentration gradient of a particular gas in a mixture differs from
its equilibrium value. eddy diffusion is the most important mixing process in the
lower atmosphere, while molecular diffusion becomes significant at the lower pressures
of the upper atmosphere.;
