| Zusammenfassung |
| The solar XUV-EUV flux is the main energy source in the terrestrial diurnal
thermosphere: it produces ionization, dissociation, excitation and heating.
Accurate knowledge of this flux is of prime importance for space weather. We
first list the space weather applications that require nowcasting and
forecasting of the solar XUV-EUV flux. We then review present models and
discuss how they account for the variability of the solar spectrum. We show
why the measurement of the full spectrum is difficult, and why it is illusory
to retrieve it from its atmospheric effects. We then address the problem of
determining a set of observations that are adapted for space weather
purposes, in the frame of ionospheric studies. Finally, we review the
existing and future space experiments that are devoted to the observation of
the solar XUV-EUV spectrum. |
