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 extinction cross sections are c6 corvette door handle largest in the size regime that st?vsugerposer aeg 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 low absorption potential, shape effects on the absorption cross sections are very small.
