Influence of long-range atmospheric transport pathways and climate teleconnection patterns on the variability of surface Pb-210 and Be-7 concentrations in southwestern Europe

The variability of the atmospheric concentration of the 7Be and 210Pb radionuclides is strongly linked to the origin of air masses, the strength of their sources and the processes of wet and dry deposition. It has been shown how these processes and their variability are strongly affected by climate...
