Instrument : Aethalometer (AETH)

Instrument Categories
Aerosols

The Aethalometer® operates on the same principle as the Particle Soot Absorption Photometer, i.e., continuously measuring the transmission of sample air through a filter substrate and the absorbing aerosol particles collected in the filter. However, it employs more wavelengths (7) and has a movable filter (tape) to allow continuous operation over long periods without requiring filter changes.

The AETH is part of the Aerosol Observing System (AOS).
