Abstract: When sampling aerosol particles from aircraft, the inlet system is the most critical item because it can strongly modify the number concentration, size distribution, and chemical composition of the particles. In this ...

Abstract: A volatility tandem differential mobility analyzer (VTDMA) was developed with the intention to measure the fraction of sulfuric acid in marine fine aerosols (Dp < 150 nm). This work focused on the design and calibration ...

Abstract: The deployment of measurement equipment in passenger aircraft for the observation of atmospheric trace constituents is described. The package of automated instruments that is installed in a one-ton-capacity aircraft freight ...

Abstract: As designed in the 1940s by Beuttell and Brewer, the integrating nephelometer offers a direct method of measuring light scattering by airborne particles without assumptions about particle composition, shape, or physical ...

Abstract: This study determined measured and Mie-calculated angular signal truncations for total and backscatter TSI, Inc., nephelometers, as a function of wavelength and for particles of known size and composition. Except for the ...
