title: Measurement of particle optical absorption, imaginary refractive index, mass concentration, and size at First International LAAP Workshop.
abstract: The modified integrating plate method was used in conjunction with ancillary equipment to obtain the absorption coefficient, specific absorption, and single-scattering albedo for a variety of generated aerosols. A computer driven multichannel optical particle counter also provided real-time output for particle size distributions. Size segregated sampling was done for appropriate aerosols, and inferences made on values for the complex refractive index. A new technique (paper in preparation) was also used for samples having low values of absorption, and results for these samples are included. These results are considered the most accurate and take precedence over values obtained by the original method (retained for completeness and inter-comparison purposes).
