| Summary: | Proposal title "Quantification of mineral dust (MD) contribution to Arctic aerosol, analysis of samples collected at the Zeppelin Observatory". Measurements carried out at the external beam set-up for atmospheric aerosol analysis of the INFN LABEC accelerator laboratory), from 7 till 7 March 2023. Hands-on mode. Aerosols interfere with the polar energy balance directly, by absorbing or scattering radiation, and indirectly by affecting cloud formation and properties, and is a function of the aerosol physical, optical, and chemical properties. Aeolian mineral dust (MD) can be a significant contributor to the Arctic aerosol and has a warming effect by absorbing radiation, as well as it decreases the surface albedo when deposited on snow and ice and enhance smelting (of snow and ice). MD particles may also be efficient scatterers of sunlight and thus can have a cooling effect. MD in the Arctic atmosphere can both be long-range transported (LRT) and originate from intrinsic sources. Atmospheric MD concentrations ... |
