Chongce ice core trapped air isotopic and elemental ratio data

This dataset contains the trapped air isotopic and elemental ratio compositions of the Chongce ice core. The ice core was drilled in 2013 on the Northwestern Tibetan Plateau (35°14' N,
81°7' E). This dataset includes: (1) the raw data of sample depth, total air content, δ18O, δ15N, δO2/N2 and δAr/N2 compositions; (2) post-depositional corrected δ18Oatm data; (3) CO2 concentrations; (4) dating result based on δ18Oatm synchronization with the Antarctic Siple Dome ice core.
