| Zusammenfassung |
| The electron temperature (Te), electron density (Ne), and two
components of the electric field were measured from the height of 90 km to 150 km
by one of the sounding rockets launched during the SEEK-2 campaign.
The rocket went through sporadic E layer (Es) at the height of 102 km–109 km
during ascent and 99 km–108 km during decent, respectively. The energy
density of thermal electrons calculated from Ne and Te shows the broad
maximum in the height range of 100–110 km, and it decreases towards the lower and
higher altitudes, which implies that a heat source exists in the height
region of 100 km–110 km. A 3-D picture of Es, that was drawn by using
Te, Ne, and the electric field data, corresponded to the computer
simulation; the main structure of Es is projected to a higher altitude along
the magnetic line of force, thus producing irregular structures of Te, Ne and electric field in higher altitude. |
