Short summary
It is important to understand atmospheric chemistry over Antarctica under a changing climate. Thus snow collected on a traverse from the coast to Dome A was used to investigate variations in snow chemistry. The non-sea-salt fractions of K+, Mg2+, and Ca2+ are associated with terrestrial inputs, and nssCl is from HCl. In general, proportions of non-sea-salt fractions of ions to the totals are higher in the interior areas than on the coast, and the proportions are higher in summer than in winter.
