Adjoint accuracy for the full Stokes ice flow model: limits to the transmission of basal friction variability to the surface

This work focuses on the numerical assessment of the accuracy of an adjoint-based gradient in the perspective of variational data assimilation and parameter identification in glaciology. Using noisy synthetic data, we quantify the ability to identify the friction coefficient for such methods with a...
