    "abstract": "We describe the first DNS-based measurement of the complete mean response of\na turbulent channel flow to small external disturbances. Space-time impulsive\nperturbations are applied at one channel wall, and the linear response\ndescribes their mean effect on the flow field as a function of spatial and\ntemporal separations. The turbulent response is shown to differ from the\nresponse a laminar flow with the turbulent mean velocity profile as base flow.",
