Indus River

This Envisat image shows western India and southern Pakistan, with the Indus River snaking through Pakistan’s Sindh province before emptying into the Arabian Sea. The red area in the lower-central portion of the image covers a seasonal salt marsh over Pakistan’s border with western India.

This image is a compilation of three passes by Envisat’s radar on 15 May, 14 July and 12 September 2011. Each is assigned a colour (red, green and blue) and combined to produce this representation. The colours reveal changes in the surface between Envisat’s passes.
