TL;DR: A detailed discussion of the strengths and limitations of the AMS measurement approach is presented and how the measurements are used to characterize particle properties are reviewed to highlight the different applications of this instrument.

TL;DR: In this article, a framework is presented for combining the information content of different equivalent diameter measurements into a single coherent mathematical description of the particles, which allows the placing of constraints on particle density, dynamic shape factor (x), and fraction of internal void space.

TL;DR: The Aerodyne Aerosol Mass Spectrometer (AMS) as mentioned in this paper was designed to measure size-resolved mass distributions and total mass loadings of volatile and semivolatile chemical species in/on submicron particles.

TL;DR: Direct measurements show that ambient atmospheric particulate black carbon absorbs less solar radiation than theory suggested, suggesting that many climate models may be overestimating the amount of warming caused by black carbon emissions.

TL;DR: The Soot Particle Aerosol Mass Spectrometer (SP-AMS) as discussed by the authors was developed to measure the chemical and physical properties of particles containing refractory black carbon (rBC).
