This paper describes the design, calibration, and testing of a prototype polar nephelometer that uses a diode laser as the light source. The instrument continuously extracts a stream of aerosol into a sensing head. The scattering of an ensembles of aerosol particles illuminated by a laser beam is measured simultaneously at 15 polar angles from 23° to 128°. Absolute calibration of the nephelometer is obtained using Freon-12 as the scattering medium and the geometry of the sensing head. The prototype has been used successfully to retrieve particle size and refractive index from a monodisperse nonabsorbing aerosol and determine the angular scattering response of atmospheric aerosols with scattering coefficients to 10-6 m-1. Problems and limitations encountered with the prototype in long term unattended operation are discussed. |
