| Zusammenfassung |
| A 1-D fluid/kinetic code is used to model WIND Imaging Interferometer measurements of the atomic
oxygen (3P-1D) red and (-1D-1S) green thermospheric dayglows at 630.0nm and
557.7nm.
This modelling is performed for different latitude and solar zenith angle conditions, in order to reproduce the
measurements all along the satellite orbit.
Results are successfully compared to the interferometer's observations, reproducing the measured
volume emission rates, together with the maximum emission altitude.
A good agreement is found regardless of the position considered along the satellite orbit,
meaning that the solar flux and the solar zenith angle influences were successfully taken into account.
Together with this model study, a four-year red and green oxygen lines set of WINDII data is
analysed with regards to those geophysical parameters.
Correlations between volume emission rates and solar flux are evaluated and it is found that the MgII index
is better suited to this kind of study than the f10.7 decimetric index. |
