DE MEERSMAN 2 1 Veritas Suite 2200 715 – 5 th Avenue SW Calgary Alberta Canada T2P 5A2 2 School of Earth and Environment University of Leeds Leeds LS2 9JT UK Summary By their very nature multicomponent data provide information on the full wavefield and therefore offer new full-wavefield solutions for the ground roll problem. Here we introduce a time domain multicomponent Singular Value Decomposition (SVD) polarization filter that is optimized to remove most ground roll energy while
