Monitoring of the atmosphere of Mars with ACS TIRVIM nadir observations on ExoMars TGO

Franck Montmessin

Abstract

The ExoMars Trace Gas Orbiter (TGO), a mission by ESA and Roscosmos started its operational scientific phase in March 2018. The Atmospheric Chemistry Suite (ACS) is a set of three spectrometers (NIR, MIR, and TIRVIM) designed to observe the Martian atmosphere in solar occultation, nadir and limb geometry [1]. The thermal infrared channel-TIRVIM is a Fourier-transform spectrometer encompassing the spectral range of 1.7-17 μm, with the best spectral resolution 0.13 cm-1. In nadir operation mode, the primary goal of TIRVIM is the long-term monitoring of atmospheric temperature and aerosol (dust and ice clouds) state from the surface to approximately 60 km. We present the results of the first half year operation in orbit around Mars.
