Really excellent, ground-breaking paper.

Some minor comments:

1. Why not work on fresh snow rather than snow stored for 7 months. Perhaps, the authors can comment on this.

2. We are told the pore size inreases 1%. How real is this? How big are the error bars?

3. "Representativity" should be changed to the real English word of "Representivity".

Short summary

In this study on temperature gradient metamorphism in snow, we investigate the hypothesis that there exists a favourable crystal orientation relative to the temperature gradient. We measured crystallographic orientations of the grains and their microstructural evolution during metamorphism using in situ time-lapse diffraction contrast tomography. Faceted crystals appear during the evolution, and we observe higher sublimation–deposition rates for grains with their c axis in the horizontal plane.
