dust map (IMAGE)
Caption
Map of the study area in the southwestern United States. Dust collectors are marked by stars corresponding to their position. The background image is an atmospheric footprint map derived from HYSPLIT-STILT backward trajectory simulations denoting the frequency with which air masses crossed different landscape positions en route to the Salt Lake City/Provo urban area during the two-year duration of this study. Warmer colors (higher values) correspond to areas more likely to have served as a regional source for dust reaching the urban collectors.
