Feeding into the new system are the improved understanding and representation of physical processes, advances in data assimilation, and diagnostic studies of predictability, all supported by comprehensive analyses of in situ and remotely-sensed observations. Innovative, even bold, modeling approaches must be considered.

This integrated modeling system can address simultaneously a wide range of science questions central to NASA’s interdisciplinary Earth system science paradigm.

The final product of this work is an advanced modeling and assimilation system that can predict the long-term evolution of climate and specifically the evolution of extreme hydroclimatic regimes such as floods and droughts on a global scale. This system can be used to investigate the impact of human activities (environmental, economic and cultural) on climate variability and change, and thereby elucidate the human-dimension of the Earth system.
