Springer-Verlag Berlin Heidelberg 2013. Exact solutions and reasonable approximations of the optical properties of nonspherical particles in the atmosphere (particularly, coarse mode mineral dust particles, ice crystals within cirrus clouds, and aviation-induced contrails) are fundamental to numerous climate studies and remote sensing applications (Chylek and Coakley, 1974; Haywood and Boucher, 2000; Ramanathan et al., 2001; Sokolik et al., 2001; Kaufman et al., 2002; Liou et al., 2000; Liou, 2002; Baum et al., 2005; Baran, 2009; Yang et al., 2010). The morphologies of realistic aerosols (Reid et al., 2003) and ice crystal habits (Heymsfield and Iaquinta, 2000) are extremely diverse. For simplicity, light scattering simulations reported in the literature are limited to a small set of well-defined nonspherical geometries such as hexagonal columns or plates, aggregates of columns or plates, bullet rosettes, circular cylinders, and ellipsoids (Asano and Yamamoto, 1975; Mishchenko and Travis, 1998; Yang et al., 2005; Bi et al., 2008; Meng et al., 2010; Xie et al., 2011).
