GRIMM 1.108. Because of its wide implication on meteorology, air quality and climatic changes, atmospheric aerosol represents one key aspect of current atmospheric research. Particulate matter is very effective in modifying the radiation field by absorbing and scattering solar and thermal radiation, thus impacting radiative transfer through the atmosphere. In particular, particles with diameter between 0.1 and 1 µm (the so-called accumulation mode) are highly effective to scatter incoming solar radiation. Additionally, aerosols act as cloud condensation and ice nuclei, thus influencing cloud properties. Aerosols also help to control the concentrations, lifetime and the physical as well as the chemical behaviour of many important trace gases by providing reaction sites and serving as carrier and/or sink for many atmospheric species. For instance, at Mt. Cimone, the mineral dust influence on tropospheric O3 concentrations has been extensively analysed Paolo Bonasoni National Research Council (CNR – Consiglio Nazionale delle Ricerche).
