We present computational results on the shape dependency of the extinction and invacare 9000 xt recliner wheelchair absorption cross sections of dustlike aerosol particles that were modeled as randomly oriented spheroids.Shape dependent variations in the extinction cross sections are largest in the size regime that is governed by the interference structure.Elongated spheroids best fitted measured extinction spectra of re-dispersed Saharan dust samples.For dust particles smaller than 1.5 μm in diameter and ferrofish a32pro low absorption potential, shape effects on the absorption cross sections are very small.
