Changes in atmospheric composition affect air quality, weather, climate, and critical constituents such as ozone while atmosphere-biosphere exchanges link terrestrial and oceanic pools within the carbon cycle and other biogeochemical cycles. Solar radiation affects atmospheric chemistry and is thus a critical factor in atmospheric composition. Atmospheric composition is central to Earth system dynamics since the atmosphere integrates surface emissions globally on time scales from weeks to years and couples a number of critical environmental issues. NASA’s research for furthering our understanding of atmospheric composition is geared to providing an improved prognostic capability for such issues, including 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?
