|
Process
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.
|
Testing
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).
