CryoGrid3: Model setup for crushed-rock railway embankment

CryoGrid 3 is a land-surface scheme dedicated to modeling of ground temperatures in permafrost environments. The model includes an explicit surface energy balance scheme, a subsurface heat transfer scheme, a water infiltration scheme, a dynamic snowpack scheme, and an excess ground-ice melt scheme. Through lateral coupling, the model is able to describe the lateral transfer of heat ad water between adjacent model tiles. The basic version of CryoGrid 3 is described in the following article:

The model has been further developed to capture linear infrastructure placed on permafrost ground (https://doi.org/10.5281/zenodo.4706881). The model version presented here has been further extended to describe a linear crushed-rock railway embankment and has been used for simulations presented in a research article submitted to Cold Regions Science and Technology:
