Caption: Figure 13.
Dielectric permittivity of the Martian near subsurface from Mars Reconnaissance Orbiter SHARAD data. The permittivity values are relevant to the top ∼5 m of the Martian subsurface. Dark gray indicates areas with no data or that are above the 1 km elevation cutoff. SHARAD data coverage is not consistent across Mars’s surface; see the data coverage map (Figure 15).
