On the origin and nature of Antarctic aerosols
In order to obtain a better understanding of the properties of the aerosols in "clean" air, a series of aerosol measurements was carried out at Syowa Station, Antarctica, from February 1977 to December 1978. From these measurements, it was found that the Aitken particle concentration, Mie...
