You can see the ring created by the melting of frozen precipitation very clearly on ZDR and CC. Clockwise from top right: Reflectivity (Z), Differential Reflectivity (ZDR), Specific Differential Phase (KDP), and Correlation Coefficient (CC). WebFactors affecting Reflectivity: Thickness, Pore Size, and Other Correlations The porosity of PTFE, relative to solid PTFE, can have a significant effect on a materials’ reflectance properties. Porous PTFE sheet samples at 2 mm thickness showed a reflectivity over 97%, and we expect the reflectance of thicker samples to be even higher.
