Aerosol hygroscopicity at a regional background site (Ispra) in Northern Italy
This study focuses on the aerosol hygroscopic properties as determined from ground-based measurements and Mie theory.Usually, aerosol ground-based measurements are taken in dry conditions in order to have a consistency within networks.The dependence of the various aerosol optical characteristics (e.g.aerosol absorption, scattering, backscattering o
