Email address nlmatell@gmail.com Phone Fax Supported platforms Windows Other platform Programming language Matlab Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2008 Does model development still take place? No If above answer is no, provide end year model development 2009 Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Source web address Source csdms web address Program license type GPL v2 Program license type other Memory requirements -- Typical run time -- 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 Upload manual if available: Model website if any Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component Not yet"Not yet" is not in the list (Yes, In progress, No but possible, No not possible) of allowed values for the "Code CMT compliant or not" property. PyMT component Is this a data component Can be coupled with:
