C22B:
Progress in Land Surface Modeling in Cold Regions for Earth System Models I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17587

Session Description:
The predictive capability of land surface models with respect to processes and properties of cold regions has advanced in recent years. Improvements to algorithms representing snowpack evolution, vegetation-snow interaction, and the thermal and hydrological properties of frozen soils offer the promise of enhanced performance in Earth System Models (ESMs), which will enable a better understanding of the response of cold regions to and interaction with changes in climate. For this session, we invite papers presenting the implementation of new or improved algorithms related to snow or land surface processes in cold regions in ESMs or their land surface components. Papers documenting the performance of large-scale models in cold regions, including those participating in the ESM Snow Model Intercomparison Project (ESM-SnowMIP) are also welcome.
