Aerosol size distribution (300 nm – 20 µm)

Aerosol concentration and size distribution of particles with optical diameter between 0.30 and 20 µm have been continuously recorded in 15-size channel by using an optical particle counter (OPC) Mod. GRIMM 1.108.

Purpose: 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

Statement: These measurements permit the determination of a fraction of fine mode (0.3µm < Dp < 1 µm) and coarse mode (1 µm <Dp< 20 µm) particles with a 1-minute time resolution. The instrument is based on the quantification of the 90° scattering of light by aerosol particles. According to the specifications, the reproducibility of the OPC in particle counting is ±2% (Putaud et al., 2004)
