Gc2d
GC2D simulates glacier evolution. The component simulates the formation and evolution of temperate valley glaciers or ice sheets on a two-dimensional topographic surface as driven by a specified meteorological setting.
Model introduction
gc2d is a two-dimensional finite difference numerical model that is driven by a calculations of glacier mass balance (snow precipitation - melt rate). The model calculates ice surface elevations above a two-dimensional terrain by solving equations for ice flux and mass conservation using explicit methods.
gc2d integrates glacier and climate simulation components explicitly, and thus has the unique ability to simulate feedbacks between the changing ice surface and the climate forcing.
The efficiency of this model allows simulation of glacial evolution over millennial timescales at spatial scales that resolve valley glaciers. Finally, from a computational standpoint, the simplicity of this model permits the investigation of significant regions of parameter space, allowing us to determine the effect of new processes or altered algorithms for them.
