Temporal variations and sources of elements in the South Pole atmosphere: 1. Nonenriched and moderately enriched elements
Abstract High‐volume particle samples were collected from 1979 to 1983 from the south pole atmosphere and analyzed by nuclear methods. The new results are combined with similar studies at the south pole. There is no trend of concentrations during 12 years of sampling, but concentrations of elements...
