Permamodel is a collection of numerical permafrost models with a range of capability and complexity. Permamodel includes multiple sets of sample inputs representing a variety of conditions and locations. The Permamodel project is intended to facilitate the broader use of permafrost models. We hope that the simple Python interfaces and open source licensing can make permafrost models accessible to a broad audience well beyond the permafrost research community, such as educators, students, and policy makers.
