Once deposited on the ground, snow is subject to microstructure transformations that, under somespecific conditions, may form faceted crystals. An experiment of air bubble migration in a monocrystalline iceblock under temperature gradient monitored with time-lapse X-ray microtomography was performed. This leadto valuable qualitative and quatitative data to evaluate phase-field modeling we recently developped
