Abstract : Some of the traces obtained from the topside sounder ionograms recorded at low latitudes are identified as being caused by propagation along magnetic field-aligned sheets of ionization. The electron-density distribution along the magnetic field line passing through the satellite obtained from one such trace is compared with the vertical electron-density distribution obtained from the regular topside F-layer traces. Close agreement of these two is obtained, indicating not only that propagation occurs along field-aligned sheets of ionization but also that radio waves propagated along the field lines are reflected very near the vertical-incidence reflection level.
