Permafrost is one of the Arctic climate indicators, and feedback of thawing permafrost to earth surface processes and vice versa is a research frontier. Observations can assess the current state of permafrost, but models are eventually essential to make predictions of future permafrost state and impacts on surface processes. In this 2hr clinic, we will present a new, easy-to-access and comprehensive cyberinfrastructure for permafrost modeling. The ‘Permafrost Modeling Toolbox’ includes three permafrost models of increasing complexity. The tools are embedded within the Community Surface Dynamics Modeling System Web Modeling Tool. We include multiple sets of sample inputs, representing a variety of climate and soil conditions and locations, to enable immediate use of the tools.
The hands-on clinic teaches students and researchers how to run and use several permafrost models with associated datasets. The presented models are envisioned to be the suitable for quick exploration of hypotheses and for teaching purposes. We will also explore options for model coupling, demonstrating an example of a model of coastal/delta sedimentation in permafrost environments.
