Аннотация: Temporal changes in snow structure and in effective heat conductivity during temperature gradient metamorphism are reported. The structure was measured by computed X-ray micro-tomography, the heat conductivity determined by measuring heat fluxes and temperatures. The structural parameters analyzed are: the sizes of ice structures and of pore space, specific surface area, curvature, and anisotropy. The temporal changes in structure and heat conductivity are compared. The heat conductivity changed up to twice from its initial value, due to changes in structure and texture, but not in density. A plateau phase in the development of the heat conductivity was observed, indicating a quasi-steady state of the structural evolution with respect to thermophysical properties of snow.
