| Zusammenfassung |
| A 3-D planetary model of the cosmic ray electron production rate q(h)
(cm-3 s-1) has been developed for the strato-mesosphere and lower
thermosphere (altitude range 30-100 km) with a 10-km step. The spectrum of
the primary cosmic rays is modelled by an analytical expression using input
data from the CREME96 model. An isotropic penetration of the cosmic rays from
the upper hemisphere is assumed in the model and a spherical shape of the
Earth's atmosphere is taken into account. The longitudinal effect of
ionisation from cosmic rays in the mesosphere and lower thermosphere is
calculated. A graphical presentation of the computational results is given
for 50 and 90 km at 0°, 40°, 50° and 70° N, S latitudes and
all longitudes with a step of 30°. The results of this paper provide a
basis for a quantitative understanding of the energetic processes of the
middle atmosphere and mechanisms affecting the thermodynamical balance of
the Earth's atmosphere. |
