SAGE III/ISS Science Team (ROSES 2023)

Atmospheric composition changes affect air quality, weather, climate, and critical constituents, such as ozone. Atmospheric exchange links 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 several environmental issues.  

NASA's research for furthering our understanding of atmospheric composition is geared toward providing an improved prognostic capability for key processes and issues, including the recovery of stratospheric ozone and its impacts on surface ultraviolet radiation, evolution of greenhouse gases and their impacts on climate, and evolution of tropospheric ozone and aerosols and their impacts on climate and air quality. 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?

Areas of Interest

This program element seeks proposals for members of the SAGE III Science Team. Proposals are sought in six topical areas. The first five areas are presented in no particular priority order, while the sixth topic, Independent Validation (Section 3.6), is deemed of somewhat lower priority. While NASA is soliciting proposals in all of the areas, it is not committing to funding proposals in each of these areas.

  • 3.1 Assessing Long-term Changes in Atmospheric Composition
  • 3.2 Aerosol and Cloud Studies
  • 3.3 Data Analysis and Modeling Efforts Using SAGE Datasets
  • 3.4 Multi-sensor Data Product Development
  • 3.5 Limb Scatter Retrieval Algorithm Development or Adaptation
  • 3.6 Independent Validation
