Multi-physics Facilitates Advancements in Land–Atmosphere Interaction

Abstract:

Observing, understanding, modeling and managing human–Earth interaction requires interdisciplinary research, which in turn requires conceptualizations from different perspectives. Rcent decades have seen developments in ensemble approaches of various forms, involving multiple models, initial/boundary conditions, model parameters, scenarios, and modeling centers. Even with a single model, whether it is for the atmospheric component or the land component, multi-physics approaches have been employed to represent complex processes that are considered for each component. Studies have emerged to assess the strengths and limitations of multi-model approaches versus multi-physics approaches. This talk will use the Noah land surface model with multi-parameterization options (Noah-MP) as an example to highlight recent advancements in multi-physics related research. The noted advancements include uncertainty quantification, research gap identification, realism improvement, and development of schemes for new processes. Finally, plant hydraulics is used to illustrate its implementatiton in Noah-MP for improved simulations of water and carbon cycles.
