Urban heat islands (UHIs) arise as a result of urbanization, which alters the thermal and radiative properties of natural landscapes. Extreme heat poses significant risks to the world’s growing urban population, and heat stress is likely to escalate with the anthropogenically induced temperature increases projected by climate models. Excessive heat, particularly when combined with humidity and/or poor air quality, not only affects human health but also impacts labor productivity and urban metabolism. Measures to mitigate UHIs can be identified by analyzing the root causes of the problem. Providing actionable and practical information to address the challenges of climate mitigation and adaptation, and engaging citizens and decision-makers from the outset through user-oriented City Climate Services (CCS), requires advanced weather models combined with data from various sources, as well as a state-of-the-art technical environment for the effective development of such services.

Therefore, theCityCLIMproject aimstodevelop an open platform and an advanced urban weather forecasting tool a high-resolution (100 m x 100 m) meteorological model for various cities in Europe using various input sources data, such as in-situ measurements, airborne, and satellite data.

The output from this high-resolution information and forecasting tool is used to alert the city and its residents in near real time and to generate impact maps for various mitigation scenarios that can be implemented in urban areas.
