Advances in subgrid parameterization of physical processes in Earth System Models
Session ID#: 160626
Session Description:
Understanding regional and global environmental changes requires dependable soil, snow, ice, hydrologic, oceanic, and atmospheric models, which may be coupled to create Earth System Models (ESMs). Since most models have constraints on horizontal resolution, a major challenge is the parameterization and representation of subgrid-scale physical processes. This challenge is especially prominent in developing scale-aware models since the dominant processes differ between different scales and components. This session welcomes submissions focusing on any processes related to subgrid variability across various components of Earth System Models, including soil, snow, ice, hydrologic, oceanic, and atmospheric components and their coupling schemes. Examples include: (1) observations and findings on specific subgrid-scale processes and spatial heterogeneity; (2) advances in approaches to deal with subgrid processes; regional to global applications of downscaling for modeling subgrid-scale processes; and (3) development of scale-aware models. This interdisciplinary session aims to gather related research across various fields, thereby inspiring discussions and advancements related to scale-aware modeling.
