The Earth is warming. Patterns of rainfall are changing. Urban life is becoming increasingly electrified. As a result of these three intersecting trends there are profound changes occurring in the atmospheric composition of cities. For example, emissions from restaurants, household cleaning solvents, and urban trees are overtaking emissions from vehicles as one of the dominant factors contributing to poor air quality. Many of these emissions are strongly temperature dependent, making air quality especially poor on the hottest days. In addition, as emissions decrease, disparities in exposure to poor air quality that reflect land use policy are becoming more evident. In this symposium, we invite contributions that address this changing landscape, including laboratory and field based observational studies, evaluation of mechanisms and assessment and prediction with numerical models.
