Starting from April 2007, black carbon is measured by a Multi Angle Absorption Photometer (MAAP, Model 5012 – Thermo Electron Corporation). Black carbon (BC) is a primary aerosol resulting from incomplete combustion processes. His main sources are fossil fuel (anthropogenic) and biomass burning (natural and anthropogenic). However the major sources of atmospheric BC are related to anthropogenic activities. Due to its chemical inertia, BC is ubiquitous in the atmosphere, present at low levels in remote areas, and higher concentrations near the sources, in urban area and near biomass burning regions. BC strongly absorbs solar radiation and it has been recognised as a driving factor of global warming: the magnitude of the direct radiative forcing due to BC can exceed that due to methane. Therefore continuous measurements of black carbon concentration in background conditions are important to determine source regions, elucidate the mechanisms of long range transport and validate both regional and global models. High-elevation monitoring sites provide important information on the not well-known free troposphere composition, in order to characterize its typical background conditions and investigate the influence of human activity on its composition.
