Fig. 3: Global relation between streaks, RSL, and dust.
A Map of slope streak (bright, white; dark, black) and RSL (red) distribution, overlain on TES albedo (<0.2 transparent, 0.2–0.26 gray, 0.26–0.32 blue31), highlighting several spatially coinciding, distinct cut-offs of slope streak and high albedo terrain (>0.26), such as in southern Arabia Terra, north-west Elysium Planitia, southern Amazonis, and north-western Tharsis. This implies that streaks can only form in the highest albedo (smallest particle size) terrains. Viking merged color mosaic in the background. B Joyplots (showing kernel density estimates) of slope streak (bright, tan; dark, solid black), RSL (red), and background (black line) MCD daily mean dust deposition rate on a horizontal surface for Ls 0°, 90°, 180°, and 270° (left34) and sensible surface heat flux for Ls 90° (northern summer) at 12, 3, 6, and 9 AM (right34). Average values indicated.
