| Zusammenfassung |
| The MICADO instrument, consisting of a
Michelson interferometer, has observed winds and temperatures during three
winter campaigns in the auroral zone, and during 2 years at the Observatoire de
Haute-Provence. The instrument observed the O(1S) oxygen emission
line. Emission from this line originates from both the E- and F-regions. A
method to separate the contribution from these two regions is presented for
cases when the thermospheric component is comparable to that for the mesosphere.
For the auroral latitudes, a mean model of the meridional and zonal neutral wind
components as a function of magnetic activity and time is presented and compared
to predictions from recent empirical models. For the mid-latitudes, several
properties of the semi-diurnal tides are shown and compared to radar
observations and predictions from recent theoretical models. |
