The main goal of the Heat and Health in Cities (H2C) French project is to improve the urban climate services to support preventive actions and policies to deal with the risk of heat and extreme heat in cities, with the Paris region (France) as a case study. In response, the three scientific objectives are identified: • Improve our understanding of the impacts of urban covers and surface heterogeneities in the city on UHI, local meteorology and air quality. • Strengthen the synergy between numerical modeling and multi-source observations to study the environmental phenomena in detail, and assess the spatial and temporal variations in population exposure to heat and air pollution, and the associated health risks. • Develop and provide information that is useful for decision-making, in terms of UHI assessment, consequences on exposure in both outdoor and indoor environment, associated health impacts, and opportunities for prevention.
