  1. The model resolution is 128 × 115, which corresponds to a rectangular grid cell size ~166 × 92 km in longitude × latitude at the equator. The atmosphere contains 20 vertical levels ranging from the surface up to an altitude of 95 km. CCN values are for both liquid and ice water clouds. LS corresponds to the solar longitude. The water mass eruption rate is taken from the total mass eruption rate assuming an H2O content of 1 wt% for Martian magmas.
