Zusammenfassung |
A comprehensive model is developed to study the 7320 Å dayglow
emission. The emission profiles are obtained with the help of the
recently developed Solar2000 EUV (Extreme Ultra Violet) flux model.
These emission profiles are used to construct the morphology of this
emission between equator and 45° N in the Northern
Hemisphere. A span of five years (2001–2005) is chosen to study the
effect of solar activity on the morphology of this emission. The
morphology is studied on 3 April which lies under the equinox
conditions. In 2001, the solar F10.7 index on the chosen date was as
high as 223.1 which is the case of solar maximum. It is found that
the intensity of this emission does not vary linearly with the F10.7
solar index. The morphology shows that the region of maximum
emission expands towards the higher latitudes as the F10.7 index
increases. |
