Web15. feb 2024 · The Z – R relationship developed by J. S. Marshall and W. M. Palmer (1948) consistent with an exponential drop-size distribution. The relationship is Z = 200 R1.6, where Z (mm 6 m -3) is the reflectivity factor and R (mm h -1) is the rainfall rate. The relationship is sometimes generalized to the form Z = aRb, where a and b are adjustable ...
