Short summary
We apply the GMI chemistry and transport model to simulate the seasonal variations of two radionuclide aerosol tracers (terrigenous 210Pb and cosmogenic 7Be) at the WMO-GAW station of Mt. Cimone during 2005, with an aim to understand the roles of transport and precipitation scavenging processes in controlling their seasonality. Results show a dominant role of precipitation scavenging in controlling the seasonality of 210Pb and 7Be concentrations at Mt. Cimone.
