Summary
The discrepancy between the observed values off 0 E and those computed on the basis of theChapman theory was examined. Taking monthly mean values of stations in various latitudes for the year 1958 it was shown, that the diurnal variation of indexn changes in higher latitudes becoming similar to that in the neighbourhood of the equator. This phenomenon may be attributed to the effect of a vertical drift produced by an overhead current system in that part of the dayside ionosphere. Further it was shown, that the variation of indexn with increasing solar activity is largely due to the increase of the recombination coefficient and that of the scale height.
