Trace gas observations by ACS MIR onboard ExoMars/TGO

International audience; The Atmospheric Chemistry Suite (ACS) package is a part of Russian contribution to ExoMars 2016 Trace Gas Orbiter (TGO) ESA-Roscosmos mission for studies of the Martian atmosphere and climate [1]. The design of the middle infrared (MIR) channel was optimized to overachieve the primary science goal of the TGO mission by accomplishing the most sensitive measurements ever of the trace gases present in the Martian atmosphere. Having both, high spectral resolution and signal to noise ratio (SNR) of acquired spectra, ACS MIR channel operates in solar occultation in the spectral range of 2.3-4.24 μm.
