Multispectral Imagery of the Air Mountains

Multispectral Imagery of the Air Mountains

Located in the Saharan Desert (northern Niger), the Air Mountains rise over one mile high, creating unique micro-climates and surface features. By combining different infrared imagery bands from the VIIRS instrument on the Suomi NPP satellite, these differences come to life. This image, taken on October 24, 2014, uses the SVI 3, 2, and 4 channels, along with hue and gamma corrections. In comparison, a true color visible image from the same time can be seen here.
