The ultra-high-sensitivity aerosol spectrometer (UHSAS) is an optical-scattering, laser-based, aerosol particle spectrometer system for sizing particles in the 60 to 1000 nanometer (nm) range [1–3].

The instrument counts particles in up to 100 user-specified sizing bins. The instrument’s laser illuminates particles, which scatter light. The system captures the peak light signals that are generated. These signals are used for particle sizing, since the amount of light scattered correlates strongly with particle size.

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