Significant upgrades to the Doppler radar emulator presented in May et al. (2007) have been made. These improvements include the ability to simulate time series data as well as dual-polarimetric data for liquid-phase hydrometeors. To facilitate the dual-polarimetric simulation, the entire scattering code has been rewritten, and now includes several different scattering models: Rayleigh, Rayleigh-Gans, Mie, and T-matrix. As an educational tool, this flexibility allows students to investigate the impact of these various scattering assumptions, including looking at the validity of these assumptions at different wavelengths. Various examples of the emulator's utility as an educational tool will be presented, as well as a summary of other work done to make the emulator significantly more user-friendly and easier to maintain.
