Urban areas play a fundamental role in local- to large-scale planetary processes via modification of heat, moisture, and chemical budgets. With urbanization continuing globally, it is essential to recognize the consequences of converting natural landscapes into a built environment. Given the capabilities of cities to serve as first responders to global change, considerable efforts are currently dedicated across cities to monitoring and understanding urban atmospheric dynamics. Various adaptation and mitigation strategies aimed to offset the impacts of rapidly expanding urban environments and influences of large-scale greenhouse gas emissions are developed, implemented, and evaluated. Tools and services tailored to cities that support climate action and resilience are rapidly evolving.
This session solicits submissions from the observational, modelling, and science-based tool development communities. We particularly welcome contributions that bridge natural and social sciences to address urban climate challenges in an integrated way. Submissions may cover urban atmospheric and landscape dynamics, urban-climate conditions under global to regional climate change including uncertainty propagation, processes and impacts due to urban-induced climate change, and the efficacy of various strategies to reduce such impacts. Studies linking urban climate dynamics with human health and well-being under extreme and compound events are especially encouraged. We also welcome techniques highlighting how cities use novel science data products and tools, including urban climate services, that facilitate planning and policies on adaptation and mitigation. Emerging approaches such as digital twins, citizen science, crowdsourcing, AI-based modelling, frugal informatics, and other innovations for climate resilience are highly encouraged.
