Radar Reflectivity Factor (z) The term 'Radar Reflectivity Factor (z)' as it applies to the area of the weather can be defined as ' z = the sum (over i) of (N_i * D_i^6), where N_i is the number of drops of diameter D_i in a pulse resolution volume. Note that z may be expressed in linear or logarithmic units. The radar reflectivity factor is simply a more meteorologically meaningful way of expressing the radar reflectivity'.
