The goal of this research is to obtain observation-based climatic distribution of the near-surface soil physical properties to be applied to large-scale climate models.

The approach is to collect the data on soil physical property and sub-ground hydro-thermal regimes through data mining and in situ observations at different climate zones. I will implement the obtained knowledge on climatic gradient of the property values in the global climate model.

As a result of this work, we will gain knowledge on climatic gradient (from the arctic to the temperate) of soil and snow physical properties (e.g., vertical distribution, changes in season) to be used in the global climate integrations.

This research will contribute to synthesis of arctic science through improvement of the subsurface physical property values and distribution, examination of the sensitivity of the modeled hydro-thermal regimes to those property values, and validation of the simulations.
