Ohne Schneemetamorphose kann man Schnee nicht verstehen

Snow metamorphism: a three week sequence in the micro-CT

The time-lapse movie shows the evolution of snow. The temperature gradient is 50°C per meter, as in many winter snowpacks. The volume observed is 0.9 × 3.6 × 3.6 mm3 of the measured field of view. The bottom of the snow is warmer than the top. Due to the non-destructive nature of the experimental technique, we can observe a cup crystal growing in an undisturbed environment. The non-destructive character of the measurements allows for a direct observation of deposition sites of the water molecules.
