Phase Phase Variables φ DP (°), DP (°), K DP (° DP (° km km -1 -1 ), ), and and δ (°) (°) φ DP φ sys m DP = φDP + φDP + δ + ES ■ φ DP is the measured two-way way differential propagational phase shift ■ φ sys DP is the system, or initial (r( = 0), φ DP ■ φ DPm is the φ DP owing to the propagation medium ■ δ is the backscatter differential phase ■ ES stands for Error Sources int 1 ∂φ K DP = – System noise 2 ∂r – Nonuniform beamfilling – Sidelobe contamination – Statistical uncertainty of estimate 4/3/01 8 METR 3223: Weather Radar (aliasing, dual-pol., and dual-Doppler) m DP Measures amount and shape Good for R
