Equivalent slab thickness data obtained at Delhi during the ascending half of this solar cycle from 1978 to 1980 have been analysed by the Chapman—Miller method to compute the lunar and solar daily variations. Significant diurnal and seasonal variations were observed for the lunar as well as the solar terms. There is no apparent correlation between these variations and sunspot activity. The occurrence of the most significant lunar term, the lunar semidiurnal component, coincides with the diffusion caused by the additional fountain effect generated by the lunar semidiurnal variation of the electric field at the equatorial region. Except for the phase, the results obtained for slab thickness differ from those reported for ionospheric electron content for the same period and location. |
