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.
