Shape dependency of the extinction and absorption cross sections of dust aerosols modeled as randomly oriented spheroids

We present computational results on the shape dependency of the extinction and absorption cross sections of dustlike aerosol particles that were modeled as randomly oriented spheroids.Shape dependent variations in the u11-200ps extinction cross sections are largest in the size regime that is governed by the interference structure.Elongated spheroids best fitted measured extinction spectra of fsu headband re-dispersed Saharan dust samples.For dust particles smaller than 1.5 μm in diameter and low absorption potential, shape effects on the absorption cross sections are very small.
