1. New perspectives in mesospheric wave dynamics and oxygen photochemistry
Abstract : The mesosphere is the region of the atmosphere between 50km to 100km, where both dynamical and photochemical aspects play important roles for the thermal balance. This thesis focuses on the following three areas for mesospheric studies: wave dynamics, oxygen photochemistry and retrieval using the optimal estimation method. READ MORE

2. O2 and OH airglow in the mesosphere through the lens of Odin/OSIRIS Infrared Imager
Abstract : Observing airglow emissions allows us to explore the chemical composition and dynamics of the upper mesosphere. The Odin satellite has routinely measured O2(a1∆g) and OH Meinel band airglow emissions from 2001 until 2015. In this thesis, the Odin/OSIRIS infrared imager data have been studied in some depth for the first time. READ MORE

3. Spectroscopic and kinetic studies of atmospheric oxygen emissions
Abstract : The terrestrial night sky spectrum Is dominated by emission features related to oxygen photochemistry. Photodissociation of molecular oxygen, the second most abundant atmospheric constituent Is the most efficient channel for converting solar electromagnetic radiation into chemical energy. READ MORE

4. Rocket-borne in situ measurements in the middle atmosphere
Abstract : The Earth's mesosphere and lower thermosphere in the altitude range 50-130 km is a fascinating part of our atmosphere. Complex interactions between radiative, dynamical, microphysical and chemical processes give rise to several prominent phenomena, many of those centred around the mesopause region (80-100 km).
