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 δ¹⁸O_atm data; (3) CO₂ concentrations; (4) dating result based on δ¹⁸O_atm synchronization with the Antarctic Siple Dome ice core.
