Dear authors,

I am pleased to announce that considering the positive feedback of the referees and the improvements brought to your revised manuscript, your paper is accepted for publication in the Cryosphere.

I just have a few suggestions concerning some newly-introduced sentences in the revised manuscript:

*l. 321: In find the sentence "For example, the age of snow..." unclear. Consider replacing it by something like: "Typically, the age of snow in the first, shallower, layers then remains between 0 and 7 days during winter and increases during spring, while the last, deeper, layers age continuously."

*l. 459: Consider amending the sentence "In addition, ..." as follows: "In addition, the better representation of the vertical density profile, that results in less dense and thus more insulating surface snow layers from November to February, leads to a better insulation of the bottom snow layer from the atmosphere and thus to higher temperatures of the bottom snow and top soil layers."

Best regards,
Guillaume Chambon / TC Topical Editor
