Arctic sea ice box model with 2-layer atmosphere

See Version v2-final on the right for an updated version of the model used in the final publication toy_model.py contains the full model equations, physical constants used, and integration scheme. 2D_parameter_sweeps.py is a driver file that calls functions from toy_model to sweep over two different model parameters simultaneously (i.e., testing all pairwise parameter combinations) using multi-threading. The default parameter values listed in 2D_parameter_sweeps can also be used to run a single model simulation.
