Dear Editor,

I have read the revised manuscript and rebuttal letter. While I think it indeed improved I still have a few minor requests for amendments. Page and numbers refer here to the edited ms provided along with the rebuttal letter.

Page 2, line 33 : permeability cannot be measureed using an integrated sphere (Gallet et al., 2009). This device measures SSA only (through NIR reflectance measurements).
Page 3, line 5 : I agree that "None of these techniques sample intrinsic permeability 5 of large snow volumes and therefore they do not capture macroscopic changes in permeability due to snow inhomogeneities and fractures." However, these methods have been used to address relationships between permeability, SSA and density, which may be easier to estimate on larger sample sizes, or to model (see e.g. Domine et al., TC 2013).

Yours sincerely,
