The experiment is devoted to: • Improve the knowledge of the characteristics of the aerosols present at the Auger Observatory: type, shape, elemental composition, by capturing the aerosols and analyzing them. • Identify their origin and trajectories. • Identify the possible relationships between the aerosols and the meteorological conditions. • Identify the seasonal variations of the aerosols. • Compare with other aerosols measurements performed at this site (optical depths obtained through the signals of the CLF and lidars, phase function obtained by the APF). • Provide complementary information for the analysis of the atmospheric attenuation of the fluorescence ligtht generated by the cosmic rays.
