Sažetak
The simulations of hourly Radon 222 (222Rn) concentrations are performed with the Unified EMEP model (Simpson et al., 2003) in order to validate different parameterization schemes for vertical mixing. In addition to the recently evaluated (Jeričević et al., 2010) operational EMEP vertical diffusion schemes K(z), the non-local O’Brien (1970) and local Blackadar (1979) schemes, as well as the non-local Grisogono scheme (e.g. Grisogono and Oerlemans, 2002), a new scheme which is local in stable boundary layer (SBL) and non-local in convective boundary layer (CBL) and based on total turbulent energy (TTE) closure (e.g., Mauritsen et. al, 2007) is implemented in the EMEP model. Hourly measurements of the 222Rn from different stations in Europe (the Cabauw tower in Netherlands, the Angus tower in Scotland, and Freiburg and Schauinsland in Germany) during the years 2005 and 2006 are compared to the corresponding modelled data.
