Web3 dec. 2024 · The Differential Reflectivity (ZDR) product shows the difference in returned energy between the horizontal and vertical pulses of the radar. Differential Reflectivity is defined as the difference between the horizontal and vertical reflectivity factors in dBZ units. Its values can range from -7.9 to +7.9 in units of decibels (dB). Web10 apr. 2024 · Since our modulation technique allows the detection of relative reflectivity changes in the order of 10 −6, and the signal can be further increased by increasing the source power (while staying in the linear regime), we expect that, for the large majority of materials, the thermal diffusivity can be measured via this optical method over extended …
