I am trying to calculate co and quad spectra for meteorological variables in order to spectrally examine momentum and energy fluxes. I noticed that the spec.pgram function returns power curves for both individual variables as well as coherence and phase information, but nothing about the co/quad spectrum. Does anyone have any experience with this and know of a way to back the cross-spectra out of this information or know of another package?
