Hairpin shaped Kelvin-Helmholtz waves are observed in tomographic PIV experiments on a micro-ramp wake. In this study, these waves are reproduced by applying BiGlobal stability theory to base flows conceived with the measurement data. The stability results converge with the number of instantaneous snapshots used for the base ow. The most unstable wavelength lies in the experimentally observed range and the flow structure closely resembles that shown in the snapshots.
