Instrument : Particle Soot Absorption Photometer (PSAP)
A particle soot absorption photometer collects aerosol particles on a substrate and measures the change in light transmission relative to a reference filter. Bulk particle absorption is derived after correcting for scattering effects.
The PSAP is part of the Aerosol Observing System (AOS).
