Full-field numerical analysis of high density cold firn.This paper aims to study the competing processes of normal grain growth, polygonization, and migration recrystallization in cold firn (very close to the density of ice).Their 2D model shows the importance of strain localization triggered by air inclusions that gives rise to locally high strain energies that drive grain boundary migration.Overall, this paper is well written and I think this is a valuable analysis and the expressions of strain localization apparent in the model show that there is much more heterogeneity in recrystallization process in ice than we usually assume.My primary concern with this paper is that some of the assumptions make it difficult, at best, to compare to the EDML firn thin sections.That does not say that the simulations aren't valuable, I just think the authors need to be upfront and clear from the beginning C1
