Aerodynamic diameter (d ae) Diameter (lm) of unit density sphere that has same terminal settling velocity in air as the particle of interest. Activity median aerodynamic diameter (AMAD) Fifty percent of the activity in an aerosol is associated with particles of aerody-namic diameter (d ae) greater than the AMAD. Applies to an aerosol where its
