Project duration: 01. July 2021 - 31. December 2024
Applicants: PD Dr. Martin Werner | Dr. Moritz Langer
PostDoc: Jan Nitzbon
Cooperation partner: AWI: Permafrost Research

The goal of PERMICE is the development of a modular permafrost model and its application within AWI-ESM. An improved understanding of the role of permafrost within the climate system is a most urgent question due to the current rapid Arctic warming. Building on the existing CryoGrid model and on the concept of modular enhancements via ESM-Tools, we therefore develop a state-of-the-art permafrost model for AWI-ESM. Model evaluation is performed by a set of (paleo)climate simulations and new climate scenario simulations are run for improved estimates of future Arctic warming.
