fenics_ice
Release to tag the model version used by Recinos et. al. (to be submitted to The Cryosphere).
This version holds changes needed in order to apply Fenics_ice error propagation framework to three West Antarctic ice streams. More information see the following link.
fenics_ice
fenics_ice is a Python code intended for Bayesian quantification of uncertainty of large-scale parameter sets within an ice-sheet flow model. the code contains a dynamic solver for ice-sheet flow which implements the Shallow-Shelf Approximation (MacAyeal et al, 1989, ) and approximates parameter covariance using a low-rank approximation to the inverse of the cost-function Hessian. The code uses Algorithmic Differentiation to find sensitivity of time-evolving Quantities of Interest to parameter sets, allowing projections of parameter uncertainty forward in time.
