SAGE III Meteor-3M L2 Monthly Cloud Presence Data (Native) V004

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:58 PM | Dataset Last Updated: June 23, 2026
g3acldb_004 is the Stratospheric Aerosol and Gas Experiment III (SAGE III) on the Meteor-3M (M-3M) platform (SAGE III/M3M) SAGE III Meteor-3M L2 Monthly Cloud Presence Data (Native) Version 4 data product. It is monthly data file coincident with solar event granules, that provides a monthly compilation of polar cloud presence from SAGE III during data capture of the granules. SAGE III obtains profile measurements of aerosol extinction, ozone, water vapor, nitrogen dioxide, nitrogen trioxide, chlorine dioxide and cloud formations throughout the mesosphere, stratosphere, and upper troposphere with a vertical resolution of 0.5 - 1 km resolution. SAGE III was a fourth generation, satellite-borne instrument and a crucial element in NASA's Earth Observing System (EOS) . The instrument was launched on the Russian M-3M spacecraft in December 2001. The M-3M and SAGE III missions were terminated on March 6, 2006, because of a power supply system failure resulting in loss of communication with the satellite. The newest SAGE mission, SAGE III on ISS, was launched in 2017.
