Dear Colleagues,

The chemical–physical and optical properties of the aerosol drive its direct and indirect climatic effects. As the aerosol may be long-range transported and the aerosol properties at any latitude may influence the planetary energy budget, both local and regional studies are welcome. As a matter of fact, the final radiative impact on a warming Artic is an actual and important issue on a global scale.

Thus, the present issue is dedicated to any study, either from experimental or modeling activities, in which aerosol properties (even in function of different sources/origins) and their optical/climatic impact are investigated from Southern Europe to the northernmost Arctic.

As most of the aerosol properties are often reported at ground level, vertical profiles measurements/simulations and cruise-based data are welcome.

Finally, aerosol chemical–physical properties should be investigated both by bulk and single particle approaches. Multidisciplinary studies which link size segregated aerosol properties (chemical–physical), fluxes, and hygroscopicity with their optical–climatic properties are encouraged.
