Example data plot showing the hydrogen chloride (HCl) detection in spectra collected by the Advanced Chemistry Suite (ACS) onboard the ESA-Roscosmos ExoMars Trace Gas orbiter. The data was collected via the solar occultation method where the instrument points through the atmosphere toward the Sun and observes how different atmospheric ingredients absorb the Sun's light. Since different chemicals have distinctive fingerprints, these observations provide a detailed inventory of the atmosphere's composition. This plot details how HCl varies with altitude for a particular set of measurements.
