Fig. 4

Top: apparent thermal inertia Γeff as a function of dust cover layer thickness δ for bedrock. Γeff has been calculated using various methods (see Methods/Experimental). Top and bottom horizontal dashed lines indicate Γ for the homogeneous rock and dust, respectively. Vertical dotted lines indicate dust layer thickness in units of the diurnal thermal skin depth (9.2 mm) of the dust. Data points are connected by straight lines to guide the eye. Error bars represent the effects of worst-case modeling errors as described in the main text. Bottom: same as top, but for dust-covered porous rock/coarse regolith
