Atmospheric science research provokes and reacts to policy and the historical connection between these subjects persists to the present. Air quality and climate hazards induce risks to exposed populations that impact public health, equity, and resilience often through compounding exposures that motivates policy. Action designed to improve air quality and reduce climate change impacts can improve health and address environmental injustices when it is supported through atmospheric science research. This session calls for research seeking to understand how mitigations and adaptations to air pollution and climate change could influence atmospheric chemistry and dynamics in the present and future and how these actions could affect health and equity. We welcome abstracts that leverage remote-sensing, statistical and earth-system modeling, ground-based observation, machine-learning approaches, and policy analysis techniques to investigate the efficacy of policies in ameliorating poor air quality, climate change, health impacts, and environmental injustices. Additionally, we seek novel research that identifies areas of policy need through advances in atmospheric science research.
