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 III (SAGE III), a NASA Langley Research Center-led mission, was launched on February 19, 2017 and installed on the International Space Station (ISS) during a 10-day robotic operation. Since March 2017, the instrument has been measuring and collecting data on the Earth’s sunscreen, stratospheric ozone, as well as other […]
