Abstract A new multidimensional mapping technique determines the three dimensional electron density distribution of the ionosphere over an area of several thousand kilometers from the time sequence of sounder data recorded at several locations within the area. Electron density profiles from five Digisonde stations in the Northeastern region of the North American continent are used to construct the electron distribution in a 30° longitude by 30° latitude region. Fourier transforms of the profile time histories over a period of 32 hours from each station determine the spectrum components. For each spectrum component a damped plane wave is fitted to the amplitudes and phases at the five stations.
