Sensitivity of Paleoreconstructions to Measurement Accuracy of the Glacier Borehole Temperature and Ice Core Geochemical Data

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.
