In this paper, a review of the present state of knowledge of solar particle emission is given, and the effect of this emission in geophysical phenomena is analyzed. It is pointed out that the particle emission can be categorized into (a) continuous plasma emission and (b) occasional emission of solar cosmic rays. The plasma emission mainly determines the shape of the magnetospheric boundary, whereas the cosmic ray emission accounts for the geomagnetic storms, intense aurorae, ionization of the upper atmosphere, and Forbush decreases in the primary cosmic radiation. In addition, some of the remaining fundamental questions to be investigated in the future are pointed out.
