ASI: Exploring the Hyperspectral Mirage

ASI: Exploring the Hyperspectral Mirage

The images shown here are captured from the hyperspectral satellite PRISMA’s L2D data and depict the volcano and oasis of Waw an Namous in the Fezzan region of Libya.

The caldera and its surroundings, which have formed relatively recently, appear much darker in color compared to the Sahara sand. This distinction is evident in both the false color image (RGB) on the left and the infrared band on the right.

The caldera contains several lakes, consisting of both fresh and salt water, which support a variety of vegetation, insects, and birds, including migratory species. These lakes are believed to be sustained by underground springs due to the limited rainfall in the area.
