ACS Mid InfraRed (MIR) channel notably provides solar occultation observations of the martian atmosphere in the 2.3 - 4.2 $\\mu$m spectral range. Here we use these observations to characterize water ice clouds before and during the MY 34 Global Dust Storm (GDS). We developed a method to detect water ice clouds with mean particle size $\\leq$ 2 $\\mu$m, and applied it to observations gathered between $L_s=165^\\circ$ and $L_s=243^\\circ$.
