Session Proposal: Hyper-resolution Land Surface Modeling: Innovations and Implementations for Global Environmental Challenges (AGU25)

GC068
Hyper-resolution Land Surface Modeling: Innovations and Implementations for Global Environmental Challenges

Session ID#: 252027

Session Description:
This session explores hyper-resolution land surface modeling, essential for accurately monitoring and predicting Earth's terrestrial water, energy, and biogeochemical cycles. The coarse spatial granularity in traditional approaches limits their ability to address critical global environmental challenges, including implications for extreme events, water security, food production, and ecosystem resilience. Hyper-resolution modeling demands resolutions as fine as 1 km globally—and finer at regional scales. Meeting this challenge requires innovations across multiple fronts: physical process development, integration of technologies like machine learning and data assimilation, and creation of high-resolution datasets for model forcing and validation. We welcome contributions addressing both process-level evaluation of model physics at fine scales and development of novel methods, datasets, and processes that enable hyper-resolution modeling applications. Submissions may cover diverse terrestrial processes—from atmosphere-land interactions to surface hydrology and river dynamics, including land-ocean interfaces.
