The Meteor-3M spacecraft was an enhanced iteration of the Meteor series and served as a Russian meteorological satellite. Its payload features SAGE III alongside a suite of additional scientific instruments. It launched December 10, 2001 and was terminated on March 6, 2006 because of a power supply system failure resulting in loss of communication with the satellite.
The mission collects data on the following:
Solar occultations are recorded twice per orbit as the Sun rises or sets from the perspective of the satellite. Lunar measurements are taken when the Moon is at least 50% illuminated and is not eclipsing the Sun.

| Orbital inclination | 99.8º |
| Weight | 5500 pounds |
| Eccentricity | 0.0024 |
| Perigee | 1,012 km |
| Period | 105 minutes |
| Path offset/revolution | 26.334º |
| Revisit time | 3 days (41 revolutions) |
