Space observations and atmospheric aerosols: noise or signal?

Atmospheric aerosols affect the flow of solar radiation through the Earth's atmosphere, and thus blur satellite images of the Earth's surface: that is, they are a source of noise. Thus, we should seek to somehow remove their effects from such images. However, aerosols are also an important player in the Earth's climate, and we should attempt to extract valuable information on them from satellite (and other) observations: here they are the signal. How can we address this dual problems?.
