Dust Storms

Contribution of Each Product


The dust RGB, day natural colour RGB, and IR 10.8 imagery each provide useful information for identifying dust. What contribution does each product make to dust detection? Select all that apply.

The correct answers are A, D, and F.

The dust RGB lets us identify dust and provides useful qualitative information about its concentration and height, making option A correct. But it does not provide information about visibility, making option B wrong.

The day natural colour RGB is not useful at night since it contains information from visible channels, making option C incorrect. But the product can detect thick dust over both land and ocean, which makes option D correct.

IR 10.8 µm lets us detect dust storms over hot land but not oceans. This makes option F correct, and option E wrong.
