Climate Change Research
Science in Space: April 2024 Everyone on Earth is touched by the effects of climate change, such as hotter temperatures, shifts in rain patterns, and sea level rise. Collecting climate data helps communities better plan for these changes and build…

SAGE III Sees Tonga Aerosols, Water Vapor Months After Eruption
A key part of NASA’s climate observing system, the Stratospheric Aerosol and Gas Experiment (SAGE) III instrument on the International Space Station (ISS) observed dramatically enhanced, very concentrated layers of stratospheric aerosol particles and water vapor as high as 42-44…

SAGE III Observes ISS Contamination Environment
Operating a science instrument aboard a crewed, frequently visited space station the size of a football field poses many challenges to data collection and quality. The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument, currently on board the International Space Station (ISS),…

First SAGE III atmospheric data released for public use
The first wave of atmospheric data from the Stratospheric Aerosol and Gas Experiment III (SAGE III), a NASA instrument that launched to the International Space Station earlier this year, is now available for public use.

SAGE III installed on its new home on the International Space Station
SAGE III is now safely installed on the outside of the International Space Station, where it will monitor ozone and aerosols in Earth’s upper atmosphere.

SAGE III passed this test, successfully locking onto the sun and completing a series of measurements. SAGE III will measure aerosols, ozone, water vapor and other gases to help scientists better understand levels of ozone in the Earth's atmosphere.

SAGE III to look back at Earth’s atmospheric ‘sunscreen’
A new instrument aboard the International Space Station will further study the ozone in Earth's atmosphere.
