OSIRIS image of atmospheric structures of Mars

Atmospheric structures can be seen in this image of Mars taken by the OSIRIS narrow-angle camera at 19:28 CET on 24 February 2007 from a distance of about 240 000 km.

The image was produced through a special combination of the green and red colour filters, emphasising the brightness difference. This image processing step enhances the structures in the atmosphere, either dust or clouds.
