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.

Check out SAGE III at the GLOBE Annual Meeting

If you are planning on attending the 19th GLOBE Annual Meeting in Los Angeles this summer, July 19-24, make sure you plan on attending one of the sessions about a great new resource we helped develop. Join the GLOBE kids- Anita, Simon, and Dennis- as they learn about aerosols in the latest Elementary GLOBE storybook, “What’s up in the Atmosphere? Exploring Sky Color.”

The kids learn concepts including air quality, aerosols, properties of light, and more all while enjoying a fun story. There are also four learning activities connected to the book and its themes. We’ll be doing two session and we’ll also have a table at registration so make sure you check us out!
