## Visible Imagery

- Visible satellite imagery is derived from reflected solar radiation from the earth-atmosphere system.
- Intensity of the image brightness depends on the albedo of the underlying surface or cloud.
- In visible imagery, different shades of grey indicate different levels of reflectivity: the most reflective surfaces are light or nearly white in tone while the least reflective surfaces are represented as black.
- Clouds are typically seen as white objects against the darker background of the earth's surface.
