CryoGrid 3 is a land-surface scheme dedicated to modeling of ground temperatures in permafrost environments. Its excess ice module Xice is capable of simulating ground subsidence and thermokarst lake formation due to melting of excess ground ice. The basic version of CryoGrid 3 and Xice is described in the following article: Westermann, S., Langer, M., Boike, J., Heikenfeld, M., Peter, M., Etzelmüller, B., & Krinner, G. (2016). Simulating the thermal regime and thaw processes of ice-rich permafrost ground with the land-surface model CryoGrid 3. Geosci. Model Dev. , 9(2), 523–546. https://doi.org/10.5194/gmd-9-523-2016 The model version of this release v1.0.0 has been extended by a hydrology scheme for unfrozen ground conditions, and schemes for the lateral transport of heat, water, and snow between adjacent parts of the simulated environment. It has been set-up to study the degradation of ice-wedge polygons as described in the following article which has been accepted for publication: Nitzbon, J., ... : {"references": ["Westermann, S., Langer, M., Boike, J., Heikenfeld, M., Peter, M., Etzelm\u00fcller, B., & Krinner, G.
