A Glossary Of Aerosol Terms
Aerosol Optical Depth (AOD)
Aerosol Optical Thickness (AOT)
- An optical measurements of light extinction used to represent aerosol amount in the entire column of the atmosphere.
- The fraction of light extinction due to particles in the
- A simple ratio of the volume of fine particles to the
total volume of particles.
PM 2.5 - particles of less than 2.5 Ám aerodynamic diameter.
CCN (Cloud Condensation Nuclei) Concentration.
These are particles that act as condensation surfaces and
encourage water droplet formation within clouds.
Particle shape - spherical, spheroid, non-spherical
Single Scattering Albedo wo (Omega Zero) – the ratio of light scattering to extinction. It indicates the relative light scattering or absorbing nature of the particles.
Radiative Transfer - The physics and mathematics of how radiation passes through a medium that may contain any combination of scatterers, absorbers, and emitters.
Aerosol Inversion -
Using the measured optical properties to infer the physical characteristics of the Aerosol
