Abstract

Naturally-occurring and artificial radionuclides in PM₁₀ aerosol samples have been systematically measured for more than 12 years at the “O. Vittori” observatory, a baseline station located in a crucial position in the middle of the Mediterranean basin under the influence of relevant atmospheric streamers crossing in this area. The database collected and herein described covers PM₁₀ mass load, ⁷Be and ²¹⁰Pb, while sporadic samples showed the occurrence of artificial radionuclides as a result of accidents such as the tsunami induced Fukushima nuclear accident or the Algeciras non-nuclear ¹³⁷Cs release. The principal scope of radioactivity monitoring at CMN has been the study of Stratosphere to Troposphere Exchange, mainly based on the variation of cosmogenic ⁷Be, while the availability of ²¹⁰Pb as well of the mass load of PM₁₀ allowed to extend the efficiency of radiotracer data to the identification of continental aerosol sources such as Saharan dust and the Balkan region. Extensive work has been and is still in progress based on the collected dataset concerning the application of global circulation models which rely on the support of objective tracers for their validation.

The most widely adopted time resolution in airborne radionuclide monitoring is on a weekly basis, which typically smooths out fluctuation due to meteorological variability leading to a remarkable loss of information.

TSP stands for Total Suspended Particulate, i.e. ambient aerosol samples collected without any size cut-off.

Until the 60’s it was believed that the main source of tropospheric ozone was the stratosphere.

The potential vorticity is defined as the specific volume times the scalar product of the absolute vorticity vector and the gradient of potential temperature. It can be described as the absolute circulation of an air parcel that is enclosed between two isentropic surfaces. Within the troposphere, the values of PV are usually low, while PV rapidly increases from the troposphere to the stratosphere due to the significant change in static stability.
