The Stratospheric Aerosol and Gas Experiment III (SAGE III) was successfully launched onboard a Meteor-3M spacecraft on December 10, 2001. The satellite is in a sun-synchronous orbit with an ascending node time of about 9 AM. Routine measurement operations began in March 2002.

The specific measurement objectives of SAGE III provide 1 km vertical resolution profiles of:

  • aerosols and clouds at seven wavelengths from the mid-troposphere into the stratosphere and where appropriate, the mesosphere;
  • O3 from the mid-troposphere to 85 km;
  • H2O from the planetary boundary layer to 50 km;
  • NO2 from the tropopause to 45 km; NO3 from 20 to 55 km;
  • OClO from 15 to 25 km;
  • O2 from the mid-troposphere to 70 km
