space for thin ice, thick ice, and OW obtained from
artificial ice grown in an outdoor tank. The other panels (b-f) show the temporal evolution of the two measure-
ments during the selected day as marked in the panel. Different days are associated with different ice thicknesses
and surface conditions as shown in the labels. Trajectories show wide range of variability except under dry snow
conditions when the data tend to cluster [
