Abstract:
Laboratory O2 clumped-isotope data (as D36 values measured at Rice University) for air occluded in ice core WDC06A spanning gas ages of 18000-21000 ky BP for the Last Glacial Maximum (LGM). Modeled atmospheric history for the LGM via outputs of the GISS-E2.1 driven and Data Assimilation (DAv2.0) driven chemical transport model incorporated into a 2-box model of the atmosphere.
