Abstract: A method and apparatus for particle counting and wavelength or angle performed in combination in order to characterize an aerosol is disclosed. In one example, data regarding particle counting (such as from an optical particle sensor) and data regarding angle or wavelength (such as from an ensemble measurement sensor) may be separately generated, with the separately generated data being analyzed in combination in order to characterize the aerosol. In another example, data regarding particle counting and regarding angle or wavelength may be generated in combination in order to characterize the aerosol.
