4.1.6 Day 1, Conduction starting at sunrise

Conduction began when the snow started accumulating. At sunrise, the temperature was 0°C (32°F) near the base of the pack and -3°C (27°F) at the top (the same as the air temperature above). This caused a small temperature gradient, with the snow next to the ground warming slightly from conduction. This process will continue as long as the adjacent ground surface stays warmer than the snowpack.

The lowest portion of the snowpack, next to the ground, is warming slowly from conduction.
