Synopsis

The stability of the Greenland Ice Sheet in a warming climate is a critical societal concern. Predicting Greenland's contribution to sea level remains a challenge as historical simulations of the past decades show limited agreement with observations. In this project, we develop a data assimilation framework that combines sparse observations and the ice sheet model PISM to produce a reanalysis of the state of the Greenland Ice Sheet from 1980 to 2020 using probabilistic filtering methods.

This repository contains scripts and functions to generate and analyze hindcasts performed with the ![Parallel Ice Sheet Model (PISM)]
