Summary: | Daily thaw depth and frozen ground depth are calculated using a frozen ground model. Oelke et al. [2004] provide details, while also referring to [Oelke et al., 2003]. Thaw depth and frozen ground are calculated using different initial model settings. In the first case, all soil down to the lower model boundary is set to sub-freezing initial temperatures. Thawing during the summer months caused the development of a thawed layer at the top with the thaw depth again decreasing during freeze-up of the thawed layer in fall. Frozen ground depth on the other hand is calculated with soil temperatures at all depths above-freezing at the beginning. Here the frozen depth increased during winter, and spring thawing eventually decreases its value. The data are presented in 24 sub-datasets of different spatial and temporal aggregations. |
