Beijing, China — The Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) hosts the Beijing node of the Global KM-Scale Hackathon 2025 from May 12 to 16, 2025. Organized under the auspices of the World Climate Research Programme (WCRP), this landmark event unites scientists worldwide to tackle critical challenges in climate science through cutting-edge kilometer-scale modeling and collaborative innovation.

Supported by international initiatives like the Earth Visualization Engines (EVE) and the Earth System Models and Observations (ESMO) program, the WCRP Global KM-Scale Hackathon 2025 fosters cross-border cooperation globally. Scientists from nine nodes — including Beijing, Hamburg, Boulder, Tokyo, and Oxford — will jointly analyze high-resolution simulations from leading models such as CAS-ESM, ICON, SCREAM, NICAM, and Unified Model, aiming to advance next-generation Earth system modeling.

Leveraging the national major scientific and technological infrastructure "Earth System Numerical Simulation Facility", the Beijing node will delve into key scientific issues such as the Asian monsoon, extreme precipitation, abnormal typhoons, Pan-Third Pole climate, and combined high-temperature and drought events. It will capitalize on China’s strengths in complex terrain simulation and Asian monsoon research to offer vital insights for the high-resolution optimization of Earth/climate system models.

As climate extremes intensify, kilometer-scale modeling offers an unparalleled level of detail in understanding regional and global phenomena. This Hackathon exemplifies how global scientific communities can illuminate pathways to resilience in an era of climate uncertainty. This event also underscores China’s pivotal role in advancing climate science innovation, with the leading-edge facilities and expertise of IAP/CAS anchoring the Beijing node.
