psap > Particle Soot Absorption PhotometerInstrument Type(s) > Baseline • External • Guest

The 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).
