H52C:
Modeling the Critical Zone: Integrating Processes and Data across Disciplines and Scales I


Session ID#: 10619

Session Description:
Critical Zone (CZ) evolution and function depend on a suite of tightly coupled processes (e.g. meteorological, hydrological, geochemical, geomorphological, and biological) that are influenced by the surface and subsurface heterogeneity over a wide range of temporal and spatial scales. The goal of CZ science is to measure and model the Critical Zone, ultimately developing a fundamental understanding and predictive ability to project the CZ response to climate change and human activities.  This session aims to bring together contributions that highlight recent model development and applications and to facilitate discussions and networking in advancing CZ sciences. We seek submissions that integrate disparate disciplinary and multiple observatory data sets to test broad questions in Critical Zone science. We also encourage contributions that demonstrate the synergy between field and experimental efforts and those that elucidate underlying processes at different scales.
