SAGE III
Stratospheric Aerosol and Gas Experiment
The Stratospheric Aerosol and Gas Experiment (SAGE III) is a satellite occultation instrument designed to observe the long-term health of the upper atmosphere. It consists of a UV/VIS/NIR spectrometer with imaging and pointing optics to precisely track the sun or moon. SAGE III is part of NASA's Earth Science Enterprise program of climate research. Launched into a sun-synchronous low-earth orbit aboard a Russian Meteor 3M spacecraft in December 2001, SAGE-III extends the long-term relationship between the United States and Russia to understand Earth's environment.
 

SAGE III

The SAGE III mission provides accurate, long-term measurements of ozone, aerosols, water vapor and other key parameters of the Earth's atmosphere. These observations are crucial for providing a better understanding of how natural processes and human activities may influence our climate. GATS provides flight operations for SAGE-III, as well as data analysis under the SOSST program.
 

SAGE III measures high-resolution vertical profiles of key components of the upper atmosphere-the most important being ozone, aerosols and water vapor. These measurements are enhancing our understanding of climate and how human activities influence it. GATS provides flight operations support for SAGE-III, as well as data analysis under the SOSST program.
