1. Observations of water vapour in the middle atmosphere
Abstract : Water vapour is the most important greenhouse gas and plays a fundamental role in the climate system and for the chemistry of the Earth's atmosphere. This thesis presents observations of water vapour in the middle atmosphere with a particular focus on the mesosphere. READ MORE

2. Seasonality and variability of stratospheric water vapour
Abstract : Stratospheric water vapour (SWV) plays a critical role in the climate system by modulating the radiation budget and influencing the stratospheric chemistry. Studying changes of SWV on global scale is helpful for our understanding of climate change. READ MORE

3. Numerical simulations of the isotopic composition of stratospheric water vapour and methane
Abstract : The middle atmosphere is an important area of the Earth's atmosphere, but our understanding of the dynamical and chemical processes in that region is still limited. Water vapour and methane both fulfil the requirements for tracers due to their long lifetimes and have frequently been used to study dynamical processes. READ MORE

4. Measuring and modelling variations in the distribution of atmospheric water vapour using GPS
Abstract : Turbulence introduce variations in the refractive index of air, which in turn result in fluctuations in the phase and amplitude of radio signals propagating through the atmosphere. Most important are the variations due to fluctuations in the water vapour field. READ MORE

5. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt
Abstract : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. READ MORE
