Cities and their associated urban areas have a much larger impact on the environment than their spatial footprint on the Earth’s surface. This is undoubtedly true at local and regional scales, but also at global scales. At this time, more than half of the world’s population lives in urban areas (80% in the United States), and the global proportion is projected to climb to 70% by 2050. Therefore, numerical models to study physics, chemistry, and biology affecting the Earth system at regional and global scales must represent the effects of urban areas on climate and the effects of a changing climate on urban areas. At the same time, it is essential to develop state-of-the-art, simple, and accurate urban models to better understand the relevant processes and also to address issues related to urban security against the spectra of chemical, biological, and radiological (CBR) hazards.
