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 first set of lunar data collected from the Stratospheric Aerosol and Gas Experiment III (SAGE III), a NASA instrument that launched to the International Space Station (ISS) in February 2017, is now available for public use. The data is available through the Atmospheric Science Data Center and includes measurements of ozone and nitrogen trioxide. […]
