  1. 11. Diurnal variation of stratospheric short-lived species

    Författare :Maryam Khosravi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chlorine monoxide; short-lived species; Arctic ClO; diurnal variation; tropical middle stratosphere; Arctic stratosphere;

    Sammanfattning : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

  3. 12. Climate Change: Models, Metrics and Meaning Making

    Författare :Erik Sterner; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate Science Literacy; Emission Metrics; Knowledge-Behavior Gap; Short-lived Climate Forcers; SF Failure; Integral Theory; Carbon Cycle; Sea Level Rise; Common Pool Resources; Resource Extraction;

    Sammanfattning : This thesis, combining research in climate science and educational science, investigates different aspects of climate knowledge. It consists of five papers and covers three major topics: emission metrics, public understanding of atmospheric CO2 accumulation, and spatial modelling of natural resource use. LÄS MER

  4. 13. Atmospheric and oceanic circulation from a thermodynamic perspective

    Författare :Aitor Aldama Campino; Kristofer Döös; Peter Lundberg; George Nurser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric circulation; Ocean circulation; Stream functions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The climate system is continuously transporting and exchanging heat, freshwater, carbon and other tracers in different spatio-temporal scales. Therefore, analysing the system from a thermodynamic or biogeochemical framework is highly convenient. LÄS MER

  5. 14. Aerosol–cloud interactions in a warming Arctic

    Författare :Linn Karlsson; Paul Zieger; Radovan Krejci; Annica M. L. Ekman; Birgit Wehner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aerosols; clouds; aerosol-cloud interactions; Arctic; climate; field studies; Environmental Sciences; miljövetenskap;

    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

  7. 15. Lifecycle of Black Carbon in the Arctic

    Författare :Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Sammanfattning : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. LÄS MER
