ACS (the Atmospheric Chemistry Suite) [1] instrument onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO) is dedicated to measurements of the Martian atmosphere, in particular implementing the solar occultation technique for sensitive measurement of trace atmospheric gases TGO has started science observations from April 2018 (Ls=162°; MY34), and has observed two major perihelion dust events, the global dust storm 2018A in June till August 2018, and the regional storm in the beginning of 2019. Here we will give a status update of the ACS results, obtained from the data collected during the first year of observations in the orbit of Mars.
