    The tracer method utilizes SF6 to account for dilution as gases exiting the cow’s mouth mix with ambient air. It is assumed that the SF6 emission exactly simulates the CH4 emission; thus, the dilution rates for SF6 and CH4 are identical. Mixing due to turbulent diffusion is much more important than molecular diffusion in the atmosphere.
