Special issue on Glacio-Isostatic Adjustment models and their associated uncertainties

Glacial Isostatic Adjustment (GIA), in response to the melting of past and present ice sheets, contributes significantly to present-day solid earth deformation, sea-level rise and temporal variations of the gravity field. GIA models are of paramount importance to disentangle the various factors contributing to deformation in formerly glaciated regions, as determined by space-borne or ground-based geodetic observations. In a global change scenario, these models are essential to estimate the contribution of the ongoing isostatic readjustment to present-day sea level. However, despite their relevance, the evaluation of their uncertainties has received little attention until the last decade. Uncertainties in GIA model predictions stem from several factors, including imperfect knowledge of a) model inputs; for example, the ice sheet chronology or the Earth rheological model and b) structural factors, including the numerical approach or the particular choice of proxy data used to constrain the model.

This special issue will address state of the art in GIA modelling on both global and regional scales, with special attention for the evaluation of the associated uncertainties.
