NASA’s research for furthering our understanding of atmospheric composition is geared to providing an improved prognostic capability for key processes and issues such as the recovery of stratospheric ozone and its impacts on surface ultraviolet radiation, the evolution of greenhouse gases and their impacts on climate, and the evolution of tropospheric ozone and aerosols and their impacts on climate and air quality. Toward this end, research within the Atmospheric Composition Focus Area addresses the following science questions:
• How is atmospheric composition changing?
• What trends in atmospheric composition and solar radiation are driving global climate?
• How does atmospheric composition respond to and affect global environmental change?
• What are the effects of global atmospheric composition and climate changes on regional air quality?
• How will future changes in atmospheric composition affect ozone, climate, and global air quality?
Objectives of NASA’s Atmospheric Composition Focus Area include monitoring and assessing the coupled effects of changes in ozone depleting substance emissions and climate variations on ozone recovery and future atmospheric composition; enabling more accurate climate forecasts based on improved understanding of the forcings of global environmental change; and developing and refining better air quality forecasts that take into account the feedbacks between regional air quality and global climate variations. Achievements in these areas via advances in observations, data assimilation, and modeling enable improved descriptions and predictions of how changes in atmospheric composition affect ozone, climate, and air quality.
