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.
A.50 SAGE III/ISS Science Team seeks proposals for members of the SAGE III Science Team. Proposals are sought in six topical areas that appear below. The first five areas are presented in no particular priority order, while the sixth topic, Independent validation, is deemed of somewhat lower priority: · Assessing Long-term Changes in Atmospheric Composition· […]
The devastating southeastern Australian bushfires that started last September spewed smoke and aerosols higher into the atmosphere than some Earth-observing instruments have ever measured. After months of hot and dry weather, the fires erupted in the heavily populated areas of New South Wales and Victoria burning millions of acres of land, destroying thousands of homes, […]
