Gases in the upper air at sunrise/sunset (Meteor-3M, native)

SAGE III Meteor-3M L2 Solar Event Species Profiles (Native) V004
atmosphere NASA LARC_CLOUD Level 2 Binary
In plain English

What it measures. The same upper-atmosphere gas profiles taken at sunrise or sunset, here stored in the instrument's original (native) file format rather than a converted one.

How it's made. Derived from the SAGE III instrument on the Meteor-3M satellite for each solar event, kept in its native format.

How & where you'd use it. Used by atmospheric chemists studying ozone and trace gases, typically those who prefer working with the data in its original form.
