Optical Absorption Characteristics of Aerosols.

Abstract

The absorption of well documented, highly absorbing submicron aerosols has been measured by means of diffuse reflectance and diffuse transmission techniques. The intent of these measurements was to compare the different techniques and to provide calibration of these absorption measurements in terms of aqueous transmission measurements. These measurements indicate that there is a consistency among the absorption techniques that the differences between absorption in an aqueous and in an air suspension need to be considered in calibrations of absorption techniques, and that the diffuse transmission and diffuse reflectance measurements using the dilution technique appear to yield consistent results. Keywords: Diffuse Transmittance; Diffuse Reflectance; Soot aerosol; Absorption; Refractive Index; Mars Ink; Nigrosine Dye; Aerosol; Bulk Absorption; Kubelkq Munk theory.
