BC concentrations overtook 8 µg/m3 during the study period due to the development of the World Mobile Congress, higher than the maximum values of a period without additional urban sources, which usually graze 3 µg/m3. Moreover, the inﬂuence of BC on aerosol optical properties such as the single scattering albedo (SSA) has been analyzed. Since BC particles absorb solar radiation, its presence decreases SSA values and its spectral variation. Finally, within the development of this study, it has been observed that, under certain circumstances, in-situ and column data can exhibit diﬀerent results5 p.application/pdfengcc-by-nc-nd (c) Villalba, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/Carboni negreAerosolsBarcelona (Catalunya)Treballs de fi de grauBlack carbonAerosolsBarcelona (Catalonia)Bachelor's thesesHigh levels of black carbon from in-situ and column measurements in Barcelonainfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
