This dataset collection contains global profiles of aerosols and clouds, ozone, nitrogen dioxide and water vapour from the Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument on board a Meteor-3M spacecraft, launched on December 10, 2001. Routine measurement operations began in March 2002 until the SAGE III mission was terminated in March 2006.

The specific measurement objectives of SAGE III provided 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; and, O2 from the mid-troposphere to 70 km.
