Data for: The transition between sand ripples and megaripples on Mars

The three figures were uploaded with the submission. All are derived from publicly available full resolution versions of the two HiRISE images described in the text: PSP_002721_2210 and ESP_016801_1300. Figures 1 and 3 have been subsampled from the original resolution in order to show a broader section of the Martian surface than could be done a full resolution. Figure 2 is a full resolution, to show the detail available in the original data.
