A remote method of identifying aerosols is described that do not have a well defined luminescence or Raman scattering. This method detects photo-thermal effects produced in and near the aerosols irradiated by a tunable excitation laser beam, which can be tuned to a peak absorption line of the aerosol or off an absorption line. The photo-thermal effects may be intermodulated light scattering or thermal IR radiation from the aerosols.
