scattering and absorption cross sections, phase functions, asymmetric parameters, and backscattering cross sections —using an accurate discrete dipole approximation method and arranged the results into an easy-to-access database. The database contains the scattering properties at frequencies from 15 to 340 GHz, with temperatures from 0° to −40°C, of particle sizes (maximum dimension) from 50 to 12,500 μm, and for 13 particle shapes.
