Impacts of Climate Change and Land Use on the Southwestern United States
Wind Erosion Vulnerability and Rainfall Mapping in the Southwestern United States

Yuma Arizona Slides


Photo taken on March 19, 1992 looking west across a fallow sandy field to the west of the Algodones Dunes complex. Surface features show a vigorous annual cover of weeds and flowers -- corresponds closely to the April 4, 1992 satellite overflight/wet season.

Same as the photo above, but acquired on June 30, 1992. The annuals have died and turned brown. The dead vegetation gives a higher visible reflectance than the green vegetation stage during the spring -- corresponds closely to the July 1, 1992 satellite overflight/dry season.
