aerosol particles

Aerosol particles are tiny solid or liquid substances suspended in air, ranging in size from nanometers to micrometers.

They can originate from natural sources like sea spray and volcanic eruptions or anthropogenic sources such as industrial emissions and vehicle exhaust.

Aerosols influence atmospheric chemistry and optics, affecting visibility and cloud formation.

Their atmospheric lifetime depends on size and composition, with smaller particles often remaining airborne longer.

Aerosols can act as cloud condensation nuclei, altering precipitation patterns and climate forcing.

Fine aerosol particles from diesel exhaust contribute to urban smog and respiratory health issues.
