Caption: Figure 24.
The probability that excess ice (more than could be stored in 40% porosity) is present in the deep subsurface (>5 m) where SHARAD reflectors exist. Dark gray indicates regions with no dielectric estimates. SHARAD data coverage is not consistent across Mars’s surface; see the data coverage map (Figure 15).
