Abstract: The simulations of hourly ²²²Rn concentrations are performed with the EMEP model to validate different parameterization schemes for vertical mixing. In addition to recently evaluated non-local vertical diffusion schemes, a new scheme which is a local and based on total turbulent energy (TTE) has been implemented in the model and evaluated. Due to its properties ²²²Rn is commonly used to study the model sub-grid mixing schemes, numerical advection schemes or to compare the performance of different models. The effects on simulated ²²²Rn concentrations are investigated providing useful information on dynamic properties and on turbulence parameterization techniques.
