Abstract:
This dataset presents values of effective thermal conductivity of 64 samples of snow, antarctic firn and porous ice in the x, y and z directions (z being the direction of gravity) at -3°C, -20°C and -60°C. Firn and porous ice samples were collected at different depth along ice cores, from 23 to 133 m, covering different levels of densification until the close-off. In addition, we provide sample type (snow types are given according the international seasonal snow classification), sample depth, sample density, sample correlation lengths in x, y, and z direction.
