I am a PhD candidate at Alfred Wegener Institute, working on the project titled “Digital Ice-Cores; Paleo-Climate Reconstruction Using Bayesian Modeling.” My project aims to reconstruct past surface temperature evolution from borehole temperature measurements. Initially, a forward heat transfer model is implemented that predicts borehole temperature profiles for a given time dependent surface temperature. This model is inverted to reconstruct the surface temperature of the past from borehole temperature measurements. Existing inversion methods for boreholes are highly model-dependent. This project aims to improve borehole inversion methods as well as the climate field reconstruction technique by optimally combining various information sources, like water isotope data from ice cores, with the spatial covariance structure from simplified climate models or reanalysis data.
