Start year development
2008
Does model development still take place?
No
If above answer is no, provide end year model development
2009

Describe input parameters
Daily average solar radiation for location (at surface).
Input format
Other input format
Matlab .mat file
Describe output parameters
Matlab variables, Matlab graphs
Output format
Other output format
Matlab variables, Matlab graphs
Pre-processing software needed?
No
Describe pre-processing software
Post-processing software needed?
No
Describe post-processing software
Visualization software needed?
No
If above answer is yes
Other visualization software
Describe processes represented by the model
Heat conduction in permafrost, lake ice growth-decay, permafrost subsidence due to excess ice
Describe key physical parameters and equations
Heat conduction equations, lake ice growth-decay equations
Describe length scale and resolution constraints
Near surface, length scale should be 5-10 cm if subsidence occurring. Deeper in permafrost, 1+ m okay.
Describe time scale and resolution constraints
Model needs daily (or smaller) timesteps.
Describe any numerical limitations and issues
Runs slowly - iterates implicit scheme. Some sort of matrix algebra might improve speed.
Describe available calibration data sets
--
Upload calibration data sets if available:
Describe available test data sets
Permafrost model can be tested with ground temperature time series at several depths. Lake model can be tested with known ice depths (though snow, not accounted for in model, can affect depth by several 10s of cm).
Upload test data sets if available:
Describe ideal data for testing
Lake temperature time series, known lake depth, underlying permafrost time series. Surface temperature time series as input (not air temperature).
Do you have current or future plans for collaborating with other researchers?

Is there a manual available?
No
