Focus Areas for SAGE III - ISS

  • Atmospheric Composition

    The Atmospheric Composition focus area consists of research on the composition of Earth's atmosphere, particularly of the troposphere and stratosphere, in relation to climate forcing, atmospheric ozone and aerosols, solar effects, air quality, and surface emissions of radiatively and chemically active source gases and particulates.

  • Carbon Cycle & Ecosystems

    This Focus Area deals with the cycling of carbon in reservoirs and ecosystems as it changes naturally, is changed by humans, and is affected by climate change.

  • Climate Variability & Change

    NASA's role in climate variability study is centered around providing the global scale observational data sets on oceans and ice, their forcings, and the interactions with the entire Earth system.
