AB: This study is aimed to analyze sensitivity of various approaches to the past surface temperature reconstructions based on the glacier borehole temperature-depth profiles and the ice-core geochemical data. Except test study we compare results of inversions for Antarctica sites: South Pole, Vostok, and Siple Dome. The reconstructions are based on the solutions of the well and ill-posed inverse problems.
