Short summary

This work presents airborne, angularly resolved measurements of light scattered by atmospheric aerosols. A classification scheme, making use of optically independent ancillary data, is developed and used to categorize each of the individual light-scattering measurements. This classification is shown to correlate very strongly with the measured aerosol scattering properties demonstrating that in situ angular light-scattering measurements alone are sufficient to identify many major aerosol types.
