SUMMARY This note documents an approach to process a suite of receiver function (RF) traces in order to identify discontinuity‐generated P ‐to‐ S ( Ps ) conversions based on the timing of their associated reverberations. It is inspired by Kumar and Bostock's method to estimate absolute P wave speeds. From RF estimates recorded in the typical source range for direct P arrivals, the method yields P to S wave speed ratios ( V P / V S ) without knowledge of crustal V P or thickness.
