Two fundamental quantities for characterizing nonlinear wave phenomena in plasmas are the spectral energy transfer associated with the energy redistribution between Fourier modes, and the linear growth rate. It is shown how these quantities can be estimated simultaneously from dual-spacecraft data using Volterra series models. We consider magnetic field data gathered upstream the Earth's quasiparallel bow shock, in which Short Large Amplitude Magnetic Structures (SLAMS) supposedly play a…
