Model is designed and calibrated for Alaska Coastal Plain.
We calibrated the model against temperature data in the subsurface from the Drew point, AK, USGS meteorological station. +
Requires an input file called: radin_dailyavg.mat
This specifies the daily average incoming radiation. +
- permafrost thermal model: calculates the … - permafrost thermal model: calculates thermal condutivity and specific heat capacity </br>- lake ice model: conduction of heat within water depending on incoming solar radiation</br>- subsiidence model: melted permafrost cells with excess ice are subsided by the excess ice content. A talik can form under a lakeice content. A talik can form under a lake +

Uppermost 10 m has high resolution gridcells (0.05m).
Below 10 m to 500 m depth, grid cells are coarser (1m). +

ThawLake1D Model couples a permafrost thermal model, a lake ice model and a subsidence model. It models heat conductio through a lake-permafrost system, evaluating temperature with depth. +
Simulations are run at daily time step
Total simulation duration is typically over 100's of years. +
This model a 1-D numerical model of permafrost and subsidence processes.
It aims to investigate the subsurface thermal impact of thaw lakes of various depths, and to evaluate how this impact might change in a warming climate. +
