How will future changes in atmospheric composition affect ozone, climate, and global air quality?
NASA expects to provide: the necessary monitoring and evaluation tools to assess the effects of climate change on ozone recovery and future atmospheric composition; improved climate forecasts based on our understanding of the forcings of global environmental change; and air quality forecasts that take into account the feedbacks between regional air quality and global climate change. Research seeks to develop quantitative understanding of: • Changes in atmospheric composition and the timescales over which they occur, • Forcings (anthropogenic and natural) that drive the changes, • Response of atmospheric trace constituents to global environmental change and the subsequent effects on global climate, and • Effects of global atmospheric chemical and climate changes on regional air quality. Chart: As depicted on the above roadmap, achievements in these areas via advances in observations, data assimilation, and modeling enable improved predictive capabilities for describing how future change
