Abstract. A novel mapping closure approximation (MCA) technique is developed to construct a model for the conditional dissipation rate (CDR) of a scalar in homogeneous turbulence. It is shown that the CDR model from amplitude mapping closure is incorrect in asymptotic behaviour for unsymmetric binary mixing. The correct asymptotic behaviour can be described by the CDR model formulated by the MCA technique. The MCA approach is outlined for constructing a successive approximation to the probability density function and conditional moment.
