Situation actuelle :

The new contributions of this study lie in the following points: (i) a wide range of snow properties (mean and Gaus- sian curvature distributions, directional correlation

In this poster, we studied the time evolution of a snow slab which undergoes a temperature gradient metamorphism based on computations performed on 3D images. Our

The choice of this snow type was guided by our objective to easily measure local phase change fluxes against the orientation of crystals relative to the tem- perature

They provide the first obser- vational evidence that temperature gradient metamorphism induces dust particle motion in snow, while no movement is observed under isothermal

In the following, we first present a simple model that estimates the matter fluxes in a snow sample submitted to temperature gradients and address the faceting issue using

Summary: In order to bring clarifications on effects of crystalline orientations of ice grains in snow during tem- perature gradient metamorphism, time-lapse diffraction

Using CellDyM, a recently developed cryogenic cell (Calonne et al, 2015), we conducted in situ time-lapse tomographic experiments on several snow and ice samples
