sp2 > Single Particle Soot PhotometerInstrument Type(s) > Baseline • External • Guest

The single-particle soot photometer (SP2) measures the soot (black carbon) mass of individual aerosol particles by laser-induced incandescence down to concentrations as low as ng/m^3.

The SP2 is part of the aerosol observing system (AOS).
