Summary

 

Our CCPP/SciDAC project has focused on the physical and computational issues of including heterogeneities in the climate treatment of land atmosphere coupling. Such heterogeneities come from either atmospheric or surface details. The objectives of this project are to: (i) provide to the community improvements to the CLM package for column land dynamics in CCSM; (ii) further develop a comprehensive package for scaling between local land columns and the CAM grid squares; (iii) integrate the CLM coupled to CAM to test the improvements provided by higher resolutions and to study the dynamics of the coupling to the climate system of surface hydrology, that is soil moisture, evapotranspiration and runoff; and (iv) develop a new approach to parameterizing convection to improve the coupling between land and atmosphere.
