| justification | This opportunity is focused on the impacts of climate variability and change on urban population and the built environment. With more than half the global population living in cities, and this number being projected to rapidly increase, this request is essential to support impacts assessments, adaptation strategies, and sustainable and resilient urban development amidst the challenges posed by a changing climate. The requested variables can support studies focused on understanding projected impacts to urban environments (both people and infrastructure). One manifestation of such impacts is the urban heat island, which requires detailed sub-daily variables to be modelled. Another strong impact of weather extremes on cities is given by surface flooding, which depends strongly on precipitation rates. Finally, some requested variable support studies into the urban PBL height, which modulates the impacts of air pollution. A vast amount of literature supports the need for this data requirement and describes case studies.
