TL;DR: The International Scientific and Technological Assessment of Sulfur Chemistry in the Antarctic Troposphere (ISCAT) was conducted at the Amundsen Scott Station in Antarctica from 15 November to 31 December 2000 as discussed by the authors.

Major ions and radionuclides in aerosol particles from the South Pole during ISCAT-2000
TL;DR: In this article, the authors analyzed aerosol samples collected at the South Pole (SP) nominally over 24-h intervals, and they were analyzed for major ions, several trace elements, and three naturally occurring radionuclides.

Douglas D. Davis,John B. Nowak,G. Chen,M. Buhr,Richard Arimoto,A. Hogan,Fred L. Eisele,Fred L. Eisele,L. Mauldin,David B. Tanner,David B. Tanner,Richard E. Shetter,Barry Lefer,Peter H. McMurry +13 more
TL;DR: In this paper, the first Austral summer measurements of NO at the South Pole (SP) were reported, which arc unique in that the levels are one to two orders of magnitude higher (i.e., median, 225 pptv) than measured at other polar sites.
Lead and mercury in aerosol particles collected over the South Pole during ISCAT-2000
Richard Arimoto,C. Schloesslin,Douglas D. Davis,A. Hogan,P. Grube,William F. Fitzgerald,Carl H. Lamborg +6 more
TL;DR: The results showed that most trace metals were below their limits of detection, and two that were not were Pb and Hg as mentioned in this paper, and the arithmetic mean concentration of filterable Hg was 0.04 ng m−3, approaching levels reported for the Arctic.
Evidence for photochemical production of ozone at the South Pole surface
James H. Crawford,Douglas D. Davis,G. Chen,M. Buhr,S. J. Oltmans,Rolf Weller,L. Mauldin,Fred Eisele,Richard E. Shetter,Barry Lefer,Richard Arimoto,A. Hogan +11 more
TL;DR: In this article, it is estimated that photochemistry could add 2.2 to 3.6 ppbv/day of ozone to surface air parcels residing on the Antarctic polar plateau.
