FS 3.118: Integrating cryosphere-atmosphere-hydrosphere dynamics

High-latitude and high-altitude cryosphere systems regulate sea levels and freshwater availability, supporting a substantial portion of the global population. These systems are undergoing rapid transformations such as diminished and earlier snowmelt, glacier retreat, intensified greening, and permafrost thaw, with cascading impacts on ecosystems and communities. This emphasizes the urgent need for improved modeling of cryosphere-atmosphere-hydrosphere interactions. However, current Earth System Models (ESMs) lack the spatial resolution to accurately represent processes at locally relevant scales. Integrating diverse datasets – including (but not limited to) stable water isotopes, novel remote sensing techniques, paleoclimate proxies like tree rings – into ESMs can refine process representation, enhancing their regional applicability. This session invites contributions ranging from field-scale measurements across diverse cryospheric regions (e.g., Alps, Nordics, Himalayas, Andes) to large-scale modeling approaches that bridge the scaling gap between local process models and global ESMs. This session is co-organized by CryoSCOPE, an EU Horizon project running from February 2025 to January 2029, aimed at enhancing cryospheric process representation in ESMs using innovative measurements across diverse region, including the Swiss Alps, Finnish Lapland, Svalbard, Iceland, Norway, and the Himalayas.
