The PIG-CES repository contains code and supporting data prepared for Pine Island Glacier modelling experiments and the associated preprint. The repository includes material used to run simulations, perform the calibration/ensemble procedure and reproduce analysis and figures. Version v0.1 is archived on Zenodo and supplements the public GitHub repository. Within OCEAN ICE, this software is linked to Deliverable D3.4 on the feasibility of using ensemble-based inversion methods for ice-sheet–ocean model initialisation.
