Main Building of the Collm Geophysical Observatory
At the Collm Observatory of the Leipzig University in the last three
decades investigations on the upper middle atmosphere have been carried
out, above all based on ground-based wind
measurements at mesopause heights (80 - 110 km) and pointing on middle
atmosphere climatology and the interaction of the different atmospheric
layers. In recent years much investigation on parts of these themes has been
done, but a systematic classification of the amount of the layer interaction
at different time scales (from the spectrum of the internal gravity waves up
to interdecadal variations) is still missing.
A contribution to this is made at the Leipzig Institute for Meteorology
(LIM). The main research themes are climatology of
winds of the upper middle atmosphere, investigations on long-term trends
and the interannual variability of the mesopause and the interaction of
different atmospheric layers, especially the stratosphere, mesosphere, and
lower thermosphere.
