Stratospheric Aerosol and Gas Experiment (SAGE)

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.

Updates from the SAGE III/ISS Visualization Team

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 well as a new ‘Highlights’ tab to showcase major stratospheric events observed by SAGE III/ISS. This new addition to the website will provide a snapshot of images detailing the event and illustrate the efforts and analyses performed by our scientific colleagues around the world in response to these atmospheric phenomena.

Be sure to check out the new ‘Comparisons’ tab that highlights measurements by ground stations that provide valuable validation data. Observations are drawn from stations around the globe contributing to the Network for the Detection of Atmospheric Composition Change (NDACC), Southern Hemisphere ADditional OZonesondes (SHADOZ), or World Ozone and Ultraviolet radiation Data Centre (WOUDC). There you can search for a specific station and view comparison plots of ozone and water vapor over the entire data record.
