Microscale urban climate modelling focuses on understanding atmospheric processes within small urban features, such as individual buildings, streets, and parks. These models, typically using computational fluid dynamics (CFD) or large-eddy simulations (LES), are critical for simulating fine-scale turbulence, heat transfer, and pollutant dispersion at resolutions down to meters. Despite significant advancements, accurately capturing the complex interactions between urban geometries, vegetation, water, and atmospheric flow remains a challenge, especially under varying meteorological conditions. Research gaps include refining turbulence modelling, integrating more detailed urban vegetation interactions, and improving the coupling between microscale and larger-scale models.

We encourage submissions on novel modelling techniques, high-resolution simulations, and experimental studies, particularly those addressing urban heat islands, urban hydrology, thermal comfort, and air quality, among other topics. Studies exploring data-driven improvements and model validation through field campaigns are also welcome. Examples of studies to be submitted to the session can be related to the advancements in CFD and LES techniques for urban environments, microscale urban heat and thermal comfort modelling, modelling of pollutant dispersion at street level, validation and integration of urban microclimates with larger scales, etc.
