Numerical mixing and unmixing occur due to diffusion and dispersion errors, but it is desirable that these errors resemble physical mixing of chemical species in the observed atmosphere. Furthermore, totals of chemical species are often important, such as total stratospheric chlorine and its chemical reaction with sunlight. This presentation reviews some previous efforts to quantify numerical errors associated with correlated chemical species.
