These long‐period surface waves can be used to give constraints on large‐scale velocity structures. Through the single‐station autocorrelation calculation of over 400 USArray stations, we find coherent signals corresponding to the Rayleigh wave that circling the Earth. The dispersion curves from the Rayleigh wave are consistent with the global average group velocity of previous studies. The travel time of these waves also shows regional variation, with the travel‐time residual almost linearly correlated with regional group velocities. Our result demonstrates the potential of imaging 3D upper‐mantle structure of extraterrestrial bodies with only one single station if it can be relocated to different sites.
