Atmospheric soot particles as seen under a transmission electron microscope are coated
      by organic and inorganic materials. Different particles collected from the atmosphere,
      even the same location and at the same time, can present very different amounts of
      coating from particle to particle. This heterogeneity has an effect on the ability
      of soot to absorb radiation.

Like Snowflakes, Soot Particles Are Unique—Affecting Climate Modeling

New understanding of modeling soot in the atmosphere underscores the importance of reducing carbon emissions.

Researchers burn kerosene in an oil lamp under a ventilation hood. They pressurize
      the air with a pump to suck the smoke into the cloud chamber. The experiments in the
      cloud chamber have allowed the researchers to understand that the longer soot particles
      are in the atmosphere, the more opportunities they have to become cloud-processed,
      and the greater the chance the particles become compacted.

As soot particles become compact in their journey through the atmosphere, they scatter and absorb light and can affect respiratory . . .
