ResumoThe ratio of aerodynamic equivalent diameter to geometric diameter was found for aerosols collected at ground-level from burning oil fields in Kuwait. Ash and soil aerosols collected using an eight-stage DRUM impactor were geometrically sized by scanning electron microscopy. Ash aggregates are shown to have a geometric diameter over an order of magnitude larger than their aerodynamic value. Additionally, ash aggregates showed changes in both particle and aggregate morphology with aerodynamic size.
