The ExoMars Trace Gas Orbiter’s Atmospheric Chemistry Suite made test measurements of the martian atmosphere on 22 November 2016 at thermal-infrared wavelengths. Such measurements will provide information on dust and ice particles, temperature profiles and concentration of gases. The inset zooms in to part of the graph with a carbon dioxide feature characteristic of the atmospheric structure, which will be useful in probing the thermal structure of the atmosphere.
The data were collected as part of an eight-day campaign to test the orbiter’s science instruments for the first time since arriving at the Red Planet on 19 October 2016.
