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.
On the fourth anniversary of its first-light measurements, we are taking a look at some of the critical data collected by NASA’s Stratospheric Aerosol and Gas Experiment III (SAGE III) aboard the International Space Station. Launched to the station in February 2017, SAGE III is the most recent in a series of SAGE instruments that […]
