What is specific differential phase?
Definition: Specific Differential Phase is a derived product that shows the gradient, or change, in Differential Phase Shift (ΦDP). Positive KDP values indicate greater phase shift in the horizontal than the vertical.
What does KDP mean on radar?
Page 22. SPECIFIC DIFFERENTIAL PHASE (KDP) - Represents the difference in phase shift between horizontal and vertical polarized returned energy due to forward propagation. - Horizontal phase shift is greater than vertical phase shift. Page 23.
What does differential reflectivity show on radar?
Recall that differential reflectivity (ZDR) can tell us about the shape of radar echoes. Hail can come in many shapes, but because it tumbles as it falls, it appears spherical to the radar. This means that hail would likely cause the ZDR to be close 0 dB.
How do you read differential reflectivity?
Differential Reflectivity
Its values can range from -7.9 to +7.9 in units of decibels (dB). Positive values indicate that the targets are larger horizontally than they are vertically, while negative values indicate that the targets are larger vertically than they are horizontally.
