Method synopsis
T-matrix and DDA computational methods to simulate radar scattering properties of ice particles with various shapes and orientations. Used to interpret observed radar signatures and constrain particle size distributions contributing to KDP signals.
Synthesized from method descriptions across 1 paper using this protocol.
Procedure from a recent peer-reviewed implementation
T-matrix scattering simulations performed for spheroidal particles using three parameters: equivolumetric diameter, axis ratio, and refractive index. Refractive index adjusted to model ice particles with varying ice densities. Calculations performed at 94 GHz and 40° elevation, averaged over 16 azimuth orientations.
105 unrimed dendritic aggregates randomly selected from snowScatt database spanning dimensions 100 μm to 4 cm. Falling behavior determined by complex interactions between aerodynamical and gravitational forces, with snowflakes falling with maximum extension oriented horizontally. DDA calculations performed at 94 GHz and 40° elevation, averaged over 16 azimuth orientations.
