Atmospheric Chemistry and Physics

This special issue addresses the problem of distinguishing aspherical from spherical particles in the atmosphere. In particular, separating liquid from ice particles in clouds and distinguishing dust, ash, bioaerosols and other types of aspherical particles from those that are spherical.

Papers that discuss the theoretical background that relates depolarization to physical features of aerosol and cloud particles are welcome, as are those that apply the theory to actual measurement of ambient particles.
