B41A:
Advances in Understanding the Scaling of Fine-Scale Spatial Hydrological and Biogeochemical Heterogeneity, Their Interactions, and Implications for Earth-System Dynamics Posters


Session ID#: 8897

Session Description:
Terrestrial ecosystems such as wetlands, permafrost tundra, and riparian zones have very high spatial- (O(1 m)) resolution hydrological and biogeochemical dynamics that are difficult to predict based on the coarse spatial resolutions (O(0.1-100 km) applied in current regional-scale models and Earth-System Models (ESMs) due to the strong nonlinear coupling between hydrology and biogeochemistry. This problem limits our ability to predict biogeochemical feedbacks to climate change. For example, researchers have attempted to address this problem by incorporating subgrid heterogeneity into ESMs and by using fine-resolution, process-rich models to inform coarser-resolution parameterizations and reduced-order models. However, much work remains before land models can realistically represent the fine-resolution processes known to affect these biogeochemical dynamics. In this session we invite modeling and observational contributions in advancing theory and methodology needed for addressing this deficiency across a wide range of spatial scales.
