By comparing TRAC-calculated ozone loss to ozone lossderived with the passive ozone method in a chemistry transport model we differentiateeffects of internal mixing and cross vortex boundary mixing on a TRAC referencecorrelation. Here, we report the successful application of TRAC on theresults of a CCM simulation.

Yet, its applicability to chemistry-climate model(CCM) data is disputed. The tracer-tracer correlation technique (TRAC) has been widely employed to infer chemical ozone loss from observations.
