| Summary: | CryoGrid is a land-surface scheme dedicated to modeling of ground temperatures in permafrost environments.Here, the one-dimensional land surface model (CryoGrid) is adapted for the application in vegetated areas by coupling a multilayer canopy model (CLM-ml v0). This model setup is used to reproduce the energy transfer and thermal regime at a study sitein mixed boreal forest in Eastern Siberia. The vegetation module forms the upper boundary layer of the coupled vegetation-permafrost model and replaces the surface energy balance equation used for common CryoGrid representations.The model is describedin the following article which has been published in Biogeosciences:Stuenzi, S. M., Boike, J., Cable, W., Herzschuh, U., Kruse, S., Pestryakova, L. A., Schneider von Deimling, T., Westermann, S., Zakharov, E. S., and Langer, M.: Variability of the surface energy balance in permafrost-underlain boreal forest, Biogeosciences, 18, 343–365, https://doi.org/10.5194/bg-18-343-2021, 2021. The parameters are set to the default values that were used for the simulations in the article. Parameters different from the default values can be specified in the main script<code>main.m</code>(general parameters, run number, etc.) and in the excel table\results\test_oldCG_334\test_oldCG_334.xlsx (run-specific parameters). To start the program, run the script<code>main.m</code>. The default output directory is.\results\.

The model is further described in this publication: Westermann, S., Langer, M., Boike, J., Heikenfeld, M., Peter, M., Etzelmüller, B., & Krinner, G. (2016).
