The Stratospheric Aerosol and Gas Experiment, SAGE, is a series of instruments designed by NASA to observe stratospheric ozone, aerosols, and water vapor from space. In the mid-1980s, scientists realized there was a problem with Earth’s protective coat of ozone...it was thinning. The SAGE family of instruments was pivotal in making accurate measurements of the amount of ozone loss in Earth’s atmosphere and helped leaders around the world institute an international treaty banning products containing harmful chemicals that destroy stratospheric ozone. SAGE is a key part of NASA’s mission to provide crucial, long-term measurements that will help humans better understand and care for Earth’s atmosphere.
The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument was launched in February 2017 to the International Space Station (ISS) and continues to provide the public and science community with world-class ozone, aerosol, and water vapor data products. The annual SAGE III/ISS Science Team meeting was held as a hybrid event hosted at NASA Langley […]
The 2025 wildfire season in Canada has been long and widespread with over 6.8 million hectares burned as of August 6, 2025, placing this year in the top 5 seasons, but less than half the size of the devastating 2023 season, according to the Canadian Wildfire Information System. Smoke from the fires traveled to the […]
The Stratospheric Aerosol and Gas Experiment III installed on the International Space Station (SAGE III/ISS) mission team announces public release of newly versioned science products. This SAGE III/ISS Version 6.0 (v6) includes Solar Level 1B, Solar Level 2, and Lunar Level 2 data products. Details of v6.0 can be found in the Release Notes and […]
In our continuing endeavor to make SAGE III data more accessible and to increase its utilization, the SAGE III/ISS team at NASA Langley Research Center launched enhancements and new features to the Quicklook and Expedited website for data visualization products. Some highlights of the changes made include easier navigation and display on mobile devices, as […]

The annual Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) Science Team Meeting was held as a hybrid event hosted at NASA Langley Research Center on October 22 and 23, with over 50 participants. Nearly 30 technical presentations were given on topics ranging from the SAGE III/ISS mission and data […]
Updated status on stratospheric aerosols using recently released public data from SAGE III/ISS Figure 1 below shows the bulk of the stratospheric aerosol layer around 10S latitude with slightly larger amounts in the Southern Hemisphere. This spatial distribution has been similar since early 2022 following the eruption of the Hunga Tonga–Hunga Haʻapai volcano in January […]
NASA’s internship programs offer opportunities year-round for students to undertake meaningful and challenging projects that truly make an impact on humanity. Selected students are provided with training, mentoring, and career development throughout their session with some of the best minds in the world. With over 100 applicants to the mission’s internship program, the Stratospheric Aerosol […]
NASA Langley’s Richard Eckman and Robert Damadeo were elected to the prestigious International Ozone Commission (IO3C) at this year’s Quadrennial Ozone Symposium, held in Boulder, Colorado, from July 15-19, 2024. Membership in the IO3C is highly selective, limited to about 30 leading scientists globally, and is determined through a peer election process. Members serve four-year […]
