Abstract: | Scattering models of aerosol particles at the G-impact site (18 July1994) are presented for a number of likely compositional
candidates. Two differing dust particle population distribution functions are taken, along with varying aerosol cloud densities,
leading to differing optical depths. A number of models including graphite, amorphous carbon, astrophysical silicate, water
ice and a number of organic compounds are discussed, but no single material provides a fully satisfactory fit to the published
observations. A porous silicate/graphite composite is found to provide a good fit to the spectral data.
