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 wave of atmospheric data from SAGE III/ISS is now available for public use through NASA’s Atmospheric Science Data Center. The data was collected from June 2017 to August 2017 and includes measurements of ozone, aerosols and nitrogen dioxide. SAGE III scientists are seeking feedback on this initial data from the international atmospheric science […]
