abstract = {Man-made climate change causes the global mean surface
temperature to rise. However, climate change also effects
the upper altitudes of the Earth’s atmosphere. Due to the
low air density and due to the efficient infrared radiation
cooling to space, temperature trends and other signals of
climate change are much more pronounced in the mesosphere
than at the ground. This work deals with the analysis and
interpretation of the emissions of excited hydroxyl radicals
(OH$^{∗}$), measured by SCIAMACHY (Scanning Imaging
Absorption Spectrometer for Atmospheric CHartographY).
SCIAMACHY is one of the ten instruments aboard ESA’s
Envisat Environmental Satellite) launched in March 2002. In
the upper mesosphere/ lower thermosphere excited OH∗ is
produced by oxygen-hydrogen-reactions. Between 83 and 95 km
altitude the reaction of ozone and atomic hydrogen, which
produces OH$^[∗]$, is the most important heat source. The
heating efficiency of the atmosphere in this region is
directly proportional to the measured emission by
OH$^{∗}$. In this work chemical heating rate, as well as
concentrations of atomic hydrogen and atomic oxygen are
derived from the measurements. The determination of atomic
hydrogen requires ozone measurements. These are provided by
GOMOS (Global Ozone Monitoring by Occultation of Stars),
which is another experiment aboard Envisat. The analysis
required the development of a complex non-LTE model, which
takes into account all production and loss mechanism of the
various vibrational states [...]},
