Atmospheric Nitrate Isotopic Analysis at Amundsen-Scott South Pole Station, A Twenty-Five Year Record
Abstract: This data set contains snow pit measurements of oxygen isotopes, <sup>17</sup>O and <sup>18</sup>O, in nitrate and ion concentrations, and surface measurements of oxygen isotopes in nitrate and in nitrate aerosols from the Amundsen-Scott South Pole Station, Antarcti...
