psap: Particle Soot Absorption Photometer

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).
