21. Improving the understanding of cloud radiative heating
Sammanfattning : Clouds play an essential role in regulating Earth’s radiation budget by reflecting and absorbing energy at different spectra. As they interact with radiation, they can radiatively heat or cool the adjacent atmosphere and the surface. LÄS MER
22. Molecular Clouds in Starburst Galaxies
Sammanfattning : Starbursts in the centres of galaxies are believed to be caused by funneling of gas towards the inner regions. Gravitational interactions between galaxies are known to cause vast rearrangements of their structure as well as induce bursts of star formation in their nuclear regions. LÄS MER
23. Aerosol–cloud interactions in a warming Arctic
Sammanfattning : Atmospheric aerosol particles are small liquid or solid particles suspended in the air. They are present in the atmosphere all around us and affect the planetary energy balance by scattering and absorbing radiation and by interacting with clouds. In model projections of future climate, aerosol–cloud interactions contribute a lot of uncertainty. LÄS MER
24. Remote sensing of ice clouds : synergistic measurements and radiative transfer simulations
Sammanfattning : This thesis primarily considers the spaceborne remote sensing of ice clouds and frozen precipitation. Ice clouds are important for hydrology and for the Earth’s radiation budget, but many properties are difficult to measure, in particular using spaceborne instruments. LÄS MER
25. Atmospheric Production and Transport of Cosmogenic 7Be and 10Be
Sammanfattning : This thesis deals with the atmospheric distribution of the cosmogenic isotopes 7Be (half-life 53 days) and 10Be (half-life 1.51 million years) as well as the anthropogenic isotope 137Cs (half-life 30 years) in aerosols and precipitation. LÄS MER
