Stratospheric Aerosol and Gas Experiment-III Meteor-3M (SAGE-III)

Click image for alternate view

Status: Completed
Mission Category: Earth Observing System (EOS)
Launch Date: December 10, 2001
Launch Location: Baikonur Cosmodrome, Russia
Actual Completion Date: March 6, 2006

The third Stratospheric Aerosol and Gas Experiment (SAGE III) Meteor-3M was the EOS component of the Russian Meteor-3M mission. SAGE III provided accurate, long-term measurements of ozone, aerosols, water vapor, and other key parameters of Earth's atmosphere. Due to a power supply system failure, communication with the satellite was lost on March 6, 2006 and the SAGE III and Meteor-3M missions were terminated.

  • Climate Variability and Change

Relevant Science Questions:

  • How is the global Earth changing?

Science Goals:

  • SAGE III provided global, long-term measurements of key components of Earth's atmosphere. It also provided measurements of temperature in the stratosphere and mesosphere. Through profiles of trace gases, such as water vapor and nitrogen dioxide, SAGE III investigated the significant role of these gases in atmospheric radiative and chemical processes.
