NASA Multifrequency Radar for Hydrometeor Phase Identification (opens in new tab)

This study investigates the potential of dual-frequency/multifrequency Doppler radar for hydrometeor phase classification and develops a phase identification algorithm using NASA airborne radar observations. Theoretical model simulations confirm a clear distinction in both Doppler velocities (V) and dual-frequency Doppler velocities (DDVs)—the difference in V at two radar frequencies—between snow and rain hydrometeors. This distinction provides a useful feature for phase identification. A sta...
