Step 1: Determine the Purpose of the Product

This natural color RGB provides a vivid depiction of northern Africa. However, it does not show the major dust front depicted by the arrows very well. That's because the input channels, 0.6 µm Vis, 0.8 µm Vis, and 1.6 µm NIR, and the resulting RGB fail to show dust in adequate contrast against the surface of the Earth. Therefore, we need a separate dust RGB for observing airborne dust. As you'll see, this is a more complex RGB than those discussed earlier.
