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?
